Calculates the remainder of a division of two floating-point numbers.

[Format]

#include <mathf.h>

float fmodf (float x, float y);

[Parameters]

x Dividend

y Divisor

[Return values]

When y is 0.0: x

When y is not 0.0: Remainder of division of x by y

[Remarks]

In the fmodf function, the relationship between parameters x and y and return value ret is as follows:

x = y * i + ret (where i is an integer)

The sign of return value ret is the same as the sign of x.

If the quotient of x/y cannot be represented, the value of the result is not guaranteed.
