The number 8 is already in its decimal form. In the decimal numeral system, whole numbers do not require a decimal point unless indicating the fractional part. For instance, you could express the number as ‘8.0’ to emphasize that it is a whole number in decimal notation.
In mathematics, decimals are commonly used to represent fractions and real numbers. However, whole numbers, like 8, can be represented directly as is, without any conversion necessary. Thus, whether you see 8, 8.0, or in scientific notation (like 8 x 100), they all represent the same quantity in decimal form.
It’s important to note that 8 is an integer, a type of number that can be whole, like 1, 2, 3, or 8. All integer values can be easily understood in decimal format because they fall under the standard base-10 system that we commonly use in daily life.
