11 The @code{c-strtold} module contains a string to number (@samp{long double})
12 conversion function operating on single-byte character strings, that operates

18 extern long double c_strtold (const char *string, char **endp);
21 In particular, only a period @samp{.} is accepted as decimal point, even
22 when the current locale's notion of decimal point is a comma @samp{,}.
