fmod
The
fmod()function takes two arguments and the floating point remainder of numerator/denominator (rounded towards zero). It is defined in <cmath> header file.
Syntax
fmod(double x, double y)
Parameters
The fmod() takes two arguments.
x: The first argument ( numerator )y: The second argument ( denominator )
Return value
Returns the floating point remainder of x/y. If the denominator y is zero, fmod() returns NaN (Not a Number).
std fmod
fmod() prototype [As of C++ 11 standard]
double fmod(double x, double y); float fmod(float x, float y); long double fmod(long double x, long double y); double fmod(Type1 x, Type2 y);
math fmod
Example : C++ fmod()
#include <stdio.h> #include <math.h> int main () { printf ( "fmod of 4.4 / 1.22 is %f\n", fmod (4.4,1.2) ); printf ( "fmod of 11.11 / 2.2 is %f\n", fmod (11.11,2.2) ); return 0; }
Output
fmod of 4.4 / 1.22 is 0.800000 fmod of 11.11 / 2.2 is 0.110000
