remquo, remquof, remquol - remainder and part of quotient

double remquo(double x, double y, int *quo);
float remquof(float x, float y, int *quo);
long double remquol(long double x, long double y, int *quo);
These functions compute the remainder and part of the quotient upon division of
x by
y. A few bits of the quotient are stored via the
quo
pointer. The remainder is returned as function value.
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.
