Function
GLibascii_formatd
Description
Converts a #gdouble to a string, using the ‘.’ as decimal point. To format the number you pass in a printf()-style format string. Allowed conversion specifiers are ‘e’, ‘E’, ‘f’, ‘F’, ‘g’ and ‘G’.
The format
must just be a single format specifier
starting with %
, expecting a #gdouble argument.
The returned buffer is guaranteed to be nul-terminated.
If you just want to want to serialize the value into a string, use g_ascii_dtostr().
