46 .TH REMQUO 3M "Jul 12, 2006" "SunOS 5.11" "Mathematical Library Functions"
48 remquo, remquof, remquol \- remainder functions
52 c99 [ \fIflag\fR... ] \fIfile\fR... \fB-lm\fR [ \fIlibrary\fR... ]
55 \fBdouble\fR \fBremquo\fR(\fBdouble\fR \fIx\fR, \fBdouble\fR \fIy\fR, \fBint *\fR\fIquo\fR);
60 \fBfloat\fR \fBremquof\fR(\fBfloat\fR \fIx\fR, \fBfloat\fR \fIy\fR, \fBint *\fR\fIquo\fR);
65 \fBlong double\fR \fBremquol\fR(\fBlong double\fR \fIx\fR, \fBlong double\fR \fIy\fR, \fBint *\fR\fIquo\fR);
71 The \fBremquo()\fR, \fBremquof()\fR, and \fBremquol()\fR functions compute the
72 same remainder as the \fBremainder()\fR, \fBremainderf()\fR, and
73 \fBremainderl()\fR functions, respectively. See \fBremainder\fR(3M). In the
74 object pointed to by \fIquo\fR, they store a value whose sign is the sign of
75 \fIx\fR/\fIy\fR and whose magnitude is congruent modulo 2^\fIn\fR to the
76 magnitude of the integral quotient of \fIx\fR/\fIy\fR, where \fIn\fR is an
77 integer greater than or equal to 3.
81 These functions return \fIx\fR REM \fIy\fR.
84 If \fIx\fR or \fIy\fR is NaN, a NaN is returned.
87 If \fIx\fR is \(+-Inf or \fIy\fR is 0 and the other argument is non-NaN, a
88 domain error occurs and a NaN is returned.
92 These functions will fail if:
101 The \fIx\fR argument is Inf or the \fIy\fR argument is 0 and the other argument
104 If the integer expression (\fBmath_errhandling\fR & \fBMATH_ERREXCEPT\fR) is
105 non-zero, then the invalid floating-point exception is raised.
111 An application wanting to check for exceptions should call
112 \fBfeclearexcept\fR(\fBFE_ALL_EXCEPT\fR) before calling these functions. On
113 return, if \fBfetestexcept\fR(\fBFE_INVALID\fR | \fBFE_DIVBYZERO\fR |
114 \fBFE_OVERFLOW\fR | \fBFE_UNDERFLOW\fR) is non-zero, an exception has been
115 raised. An application should either examine the return value or check the
116 floating point exception flags to detect exceptions.
