NAME

gcvt - convert a floating-point number to a string  

SYNOPSIS

#include <stdlib.h>

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

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

gcvt():

Since glibc 2.12:
(_XOPEN_SOURCE >= 500) ! (_POSIX_C_SOURCE >= 200112L)
    || /* Glibc since 2.19: */ _DEFAULT_SOURCE
    || /* Glibc versions <= 2.19: */ _SVID_SOURCE
Before glibc 2.12:
_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 significant 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).
