Converts given number to a list representation.
Given an IEEE 754 float, computes the shortest, correctly rounded list of digits that converts back to the same Double value when read back with String.to_float/1. Implements the algorithm from "Printing Floating-Point Numbers Quickly and Accurately" in Proceedings of the SIGPLAN '96 Conference on Programming Language Design and Implementation.
Returns a tuple comprising a charlist for the integer part, a charlist for the fractional part and an integer for the sign.
