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:

 - :ref:`PR_strtod`
 - :ref:`PR_dtoa`
 - :ref:`PR_cnvtf`

Gay's implementation is inspired by these two papers.
