| The @code{c-strtold} module contains a string to number (@samp{long double}) |
| conversion function operating on single-byte character strings, that operates |
| as if the locale encoding was ASCII. |
| (The "C" locale on many systems has the locale encoding "ASCII".) |
| |
| The function is: |
| @smallexample |
| extern long double c_strtold (const char *string, char **endp); |
| @end smallexample |
| |
| In particular, only a period @samp{.} is accepted as decimal point, even |
| when the current locale's notion of decimal point is a comma @samp{,}. |
