8 fesetprec, fegetprec \- control floating point rounding precision modes
26 The IEEE 754 standard defines rounding precision modes for systems that always
27 deliver intermediate results to destinations in extended double precision
29 double precision results (in the absence of underflow and overflow) with only
33 The \fBfesetprec()\fR function sets the current rounding precision to the
34 precision specified by \fIprec\fR, which must be one of the following values
44 round to single precision
55 round to double precision
66 round to extended double precision
71 The default rounding precision when a program starts is \fBFE_LDBLPREC\fR.
74 The \fBfegetprec()\fR function returns the current rounding precision.
79 rounding precision is established and 0 otherwise.
