What Is The Decimal Representation Of 2 10 – Humans are comfortable working with numbers expressed using a decimal notation that is based on 10 unique digits (0, 1, 2, 3, 4, 5, 6, 7, 8, and 9), but computers work with information using a binary notation that is limited to only two unique digits (0 and 1). Although we will not complete the calculations using binary numbers, you will see examples of instrumental methods, such as FT-NMR, where data analysis algorithms (the Fourier transform in this case) require the number of data points to be a power of two. It is therefore useful to be familiar with how we represent numbers in both decimal and binary form.
My university was founded in 1837, which is a decimal expression for the year. Each of these four digits represents a power of 10, a fact that is evident when we read the number aloud: one thousand eight hundred and thirty-seven, or, when we write it like this

Figure (PageIndex). Three notations are used to represent a number with (a) decimal digits and powers of 10 and (b) binary digits and powers of 2. The same number is represented in both (a) and (b).
[(1 times 1024) + (1 times 512) + (1 times 256) + (0 times 128) + (0 times 64) + (1 times 32) + (0 times 16) + (1 times 8) + (1 times 256) + (1 times 128) + (0 times 64) + (1 times 32) + (0 times 1 6) + (1 times 8) + (1 times 4) 1 times 1 s) 1 times (1 times 1 s) + (1 times 4) + (0) (1 times 4) + (0) ]
Each power of two also represents a place; thus it is the second 0 from the right in a sixteenth place. Figure (PageIndexb) provides a visual representation of these ways of expressing a binary number.
There are many online calculators you can use to convert between decimal and binary representations of numbers, like this one. However, it helps to be comfortable with manually converting numbers. Converting a binary number to its decimal equivalent is simple, as we showed above for the binary representation of the year my university was founded

There are two types of decimal representation of rational numbers, such as repeating terminating and non-terminating.
The non-terminating decimal form of a rational number could only be a repeating decimal. To represent these decimal forms, we need to use number lines. There are some unique procedures for representing the rational number in its decimal form. In this article we will look at the decimal representations of rational numbers.
Each of the numbers (frac, , frac}}, , frac}, , frac}) are rational numbers, (0) is a rational number, since we can write (0 = frac). The natural numbers, (1 = frac, , 2 = frac, , 3 = frac) and so on are rational numbers. Similarly, every integer is a rational number. If (m) is an integer, then we can write it as (frac), which is a rational number. Every fraction is a rational number. Let (frac) be a fraction. Thus (a) and (b) are integers and (b n and 0).
Decimal numbers that have a finite number of digits after the decimal point are trailing decimal numbers. Their number of decimal places is limited. These decimal numbers are called exact decimal numbers.
Working With Binary Numbers
We can represent these decimal numbers in the form (frac) where (q ne 0) or we can represent decimal numbers as rational numbers.
(2,665) is represented as (frac}}) when (p = 2665)and (q = 1000). Thus (2.665) is the decimal form of the rational number (frac}}).
Suppose we divide it into (10)equal parts and mark each division point as the figure above. So the first character to the right of (2) will represent (2.1), the second (2.2) and so on. You may find it a bit difficult to see these dividing points between (2) and (3) in the figure above. To get a clear view, you can also take a magnifying glass and look at the part between (2) and (3).
Now (2.665) is between (2.6) and (2.7). So let’s focus on the part between (2,6) and (2,7). Let’s imagine that we divide it again into (10) equal parts and mark each division point as shown in the figure. The first symbol represents (2.61), the next (2.62) and so on. Let’s zoom in to see it clearly.
Decimal Versus Binary Representation Of Numbers In Computers
We call this process of seeing the representation of numbers on the number line as successive magnification through a magnifying glass. We have thus noted that it is possible, with sufficient successive magnification, to think of the position of a rational number with a finite decimal representation on the number line.
Now let’s try to imagine the arrangement of rational numbers with a recurring decimal representation that does not end on the number line. We can look at suitable intervals with a magnifying glass and see the position of the number on the number line by successive or continuous magnification.
Decimal numbers that have an infinite number of digits after the decimal point are called non-terminating. Decimal numbers have an infinite number of digits after the decimal point. Digits that repeat at equal intervals after the decimal point are known as repeating decimals.
For example, (}}…}, }}…}, }}…}, }}…) etc. are the repeating decimals. We can represent recurring decimal numbers in the form (frac) where (q ne 0) or we can represent these decimal numbers as rational numbers.

The decimal expansion of (frac) is (0.333333). Here the remainder is (1) in each step and the divisor is (3).
We represent these decimals on the number lines. Now we continue with successive enlargements and successively reduce the lengths of the sections of the number line where (5.3overline 7 ) is located. (5.3overline 7 ) is the decimal form of the rational number. First we see that (5.3overline 7 ) lies between (5) and (6). In the next step we find (5.3overline 7 ) between (5.3) and (5.4).
To get a clearer accurate picture of the representation, we divide this part of the number line into (10) equal parts and use a magnifying glass to observe that (5.3overline 7 ) lies between (5.377) and (5.378). Now to observe (5.3overline 7 ) more precisely, let us divide the section between (5.377) and (5.378) into (10)identical parts and look at the representation of (5.3overline 7 ) in the given figure. Note that (5.3overline 7 ) is located closer to (5.3778) than (5.3777).
Note: We can continue in this way indefinitely, successively looking through a magnifying glass and at the same time imagining the decrease in length of the part of the number line where (5.3overline 7 ) is located. The size of the part of the line we specify depends on how accurately we would like to show the position of the number on the number line.

The decimal form of (frac}}) is (2.8) Now let’s take a closer look at the part of the number line between (2) and (3).
Therefore, to find its decimal form, we have to apply the long division method. Consider e.g. (frac}).
Suppose we divide it into (10)equal parts and mark each division point as the figure above. So the first character to the right of (1) will represent (1.1), the second (1.2) and so on. You may find it a bit difficult to see these dividing points between (1) and (2) in the figure above. To get a clear view, you can also take a magnifying glass and look at the part between (1) and (2).
A rational number can be represented as a decimal number. There are two types of decimal representation of rational numbers as terminating and repeating decimal numbers. To represent the decimal forms of rational numbers, we should use number lines. There are some specific rules for representing the rational number in its decimal form. This article explained decimal representations of rational numbers and showed some examples of decimal representations of rational numbers.

D.1. How to find the decimal of a rational number? Answer: Using the long division method, we can find the decimal form of any rational number. There is a special method for finding the finite decimal expansion of a rational number whose denominator has no prime factors other than (2) and (5) gives a finite decimal number. The rational number whose denominator has prime factors other than (2) and (5) yields a non-finite recurring decimal.
