Function

GLibascii_formatd

Declaration [src]

gchar*
g_ascii_formatd (
  gchar* buffer,
  gint buf_len,
  const gchar* format,
  gdouble d
)

Description [src]

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().
