    fp_to_long:long(infp:long,roundingMode:long,exact:long)
.fi
.SH "ARGUMENTS"
.PP
\fIinfp\fR
.RS 4
the 64 bit floating point stored in long
.RE
.PP
\fIroundingMode\fR
.RS 4
through 0\-6, which are round to nearest even, minMag, min, max, near maxMag and round to odd
.RE
.PP
\fIexact\fR
.RS 4
the boolean value, if exact is 1 than raising inexact exception, otherwise ignore the exception\&.
.RE
.SH "DESCRIPTION"
.PP
Given a 64 bit floating point, which is stored in long, use the long value to initiate self\-defined float64_t type, then apply the f64_to_i64 function to get the string representation\&.
