ret fmod(x, y)

Parameters

Item	Description
x	[in] The floating-point dividend.
y	[in] The floating-point divisor.

Return Value

The floating-point remainder of the x parameter divided by the y parameter.

Remarks

The floating-point remainder is calculated such that x = i * y + f, where i is an integer, f has the same sign as x, and the absolute value of f is less than the absolute value of y.
