C++ Math fmod()

The function finds the floating point remainder of numerator/denominator and rounded towards zero.

Formula of fmod:

where 't' is the truncated value of numerator/denominator.

Syntax

Consider a numerator 'n' and denominator 'd'. Syntax would be:

Parameter

n:The value of numerator.

d:The value of denominator

Return value

It returns the floating point remainder of n/d.

Note: If the value of denominator is zero, then fmod() function will return NAN(Not a Number).

Example 1

Let's see a simple example of having same types of arguments.

Output:

The values of numerator and denominator are :4.2 , 7.8
fmod of these values is :4.2

Example 2

Let's see the simple example of having different types of arguments.

Output:

The values of numerator and denominator are :7.8 , 9
fmod of these values is :7.8

Example 3

Let's see the simple example when the value of denominator is zero.

Output:

The values of numerator and denominator are :16.7 , 0
fmod of these values is :-nan
