to_str

Converts a double to a string, using the '.

' as decimal point.

This function generates enough precision that converting the string back using ascii_strtod gives the same machine-number (on machines with IEEE compatible 64bit doubles). It is guaranteed that the size of the resulting string will never be larger than G_ASCII_DTOSTR_BUF_SIZE bytes.

Parameters:

buffer	A buffer to place the resulting string in
buf_len	The length of the buffer.
d	The double to convert

Returns:

The pointer to the buffer with the converted string.
