gcvt

GCVT(3) 						     Linux Programmer's Manual							   GCVT(3)

NAME

       gcvt - convert a floating-point number to a string

SYNOPSIS

       #include <stdlib.h>

       char *gcvt(double number, size_t ndigit, char *buf);

   Feature Test Macro Requirements for glibc (see feature_test_macros(7)):

       gcvt(): _SVID_SOURCE || _XOPEN_SOURCE >= 500

DESCRIPTION

       The gcvt() function converts number to a minimal length null-terminated ASCII string and stores the result in buf.  It produces ndigit sig-
       nificant digits in either printf(3) F format or E format.

RETURN VALUE

       The gcvt() function returns the address of the string pointed to by buf.

CONFORMING TO

       Marked as LEGACY in POSIX.1-2001.  POSIX.1-2008 removes the specification of gcvt(), recommending the use  of  sprintf(3)  instead  (though
       snprintf(3) may be preferable).
