function::fp_to_string − Convert 64 bit floating point to string
fp_to_string:string(infp:long,precision:long)
infp
the 64 bit floating point stored in long
precision
number of digits after decimal point
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.
