NAME
fmod,
fmodf
- floating-point remainder function
LIBRARY
Math Library (libm, -lm)
SYNOPSIS
double
fmod(
double x
, double y
)
float
fmodf(
float x
, float y
)
DESCRIPTION
The
fmod(
)
function computes the floating-point remainder of
x
/
y
.
RETURN VALUES
The
fmod(
)
and
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(
)
function returns zero is implementation-defined.

STANDARDS
The
fmod(
)
function conforms to
ANSI X3.159-1989 (``ANSI C89'') .
