SYNOPSIS
fp_to_long:long(infp:long,roundingMode:long,exact:long)
ARGUMENTS
infp
the 64 bit floating point stored in long
roundingMode
through 0-6, which are round to nearest even, minMag,
min, max, near maxMag and round to odd
exact
the boolean value, if exact is 1 than raising inexact
exception, otherwise ignore the exception.
DESCRIPTION
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.
