Floating Point Number to String Conversion

NSPR provides functions that convert double-precision floating point numbers to and from their character string representations.

These conversion functions were originally written by David M. Gay of AT&T. They use IEEE double-precision (not IEEE double-extended) arithmetic.

The header file prdtoa.h declares these functions. The functions are:

Gay's implementation is inspired by these two papers.
