NAME    [Toc]    [Back]

     fmod, fmodf -- floating-point remainder functions

LIBRARY    [Toc]    [Back]

     Math Library (libm, -lm)

SYNOPSIS    [Toc]    [Back]

     #include <math.h>

     double
     fmod(double x, double y);

     float
     fmodf(float x, float y);

DESCRIPTION    [Toc]    [Back]

     The fmod() and the fmodf() functions compute the floating-point remainder
     of x/ y.

RETURN VALUES    [Toc]    [Back]

     The fmod() and the fmodf() functions return the value x-i*y, for some
     integer i such that, if y is non-zero, the result has the same sign as x
     and magnitude less than the magnitude of y.  If y is zero, whether a
     domain error occurs or the fmod() and the fmodf() function returns zero
     is implementation-defined.

SEE ALSO    [Toc]    [Back]

STANDARDS    [Toc]    [Back]

     The fmod() function conforms to ISO/IEC 9899:1990 (``ISO C89'').
