remquo, remquof, remquol — remainder and part of quotient
||long double x,|
|long double y,|
These functions compute the remainder and part of the
quotient upon division of
y. A few bits of the quotient
are stored via the
quo pointer. The remainder is
returned as the function result.
The value of the remainder is the same as that computed by the remainder(3) function.
The value stored via the
quo pointer has the sign of
x / y and agrees with
the quotient in at least the low order 3 bits.
For example, remquo(29.0, 3.0) returns −1.0 and might store 2. Note that the actual quotient might not fit in an integer.
On success, these functions return the same value as the analogous functions described in remainder(3).
y is a NaN, a NaN is
x is an
not a NaN, a domain error occurs, and a NaN is returned.
y is zero, and
x is not a NaN, a
domain error occurs, and a NaN is returned.
See math_error(7) for information on how to determine whether an error has occurred when calling these functions.
The following errors can occur:
xis an infinity or
yis 0, and the other argument is not a NaN
An invalid floating-point exception (
FE_INVALID) is raised.
These functions do not set
