Verifying for double-precision number

Writing functions:

isfloat(x)

Returns 1 if the value of a variable to store the fractional number (double precision), otherwise returns 0.

The function of checking the number for double precision

In modern programming, there are several data types for representing floating-point numbers, and one of the most common is the double-precision numeric type. To ensure the accuracy of calculations with fractional numbers, the system of using double-precision numbers has become common practice in many programming languages.

In this regard, it becomes necessary to check whether a given number is a double precision number.

Thus, the "isfloat()" function is a convenient tool for checking a number for double precision. Using it will help developers verify the data they are working with and provide more accurate calculations with fractional numbers.
