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

NAME

     qecvt, qfcvt, qgcvt - convert a floating-point number to a string

SYNOPSIS

     #include <stdlib.h>

     char *qecvt(long double number, int ndigits, int *decpt, int *sign);

     char *qfcvt(long double number, int ndigits, int *decpt, int *sign);

     char *qgcvt(long double number, int ndigit, char *buf);

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

     qecvt(), qfcvt(), qgcvt(): _SVID_SOURCE

DESCRIPTION

     The  functions  qecvt(), qfcvt(), and qgcvt() are identical to ecvt(3),
     fcvt(3), and gcvt(3) respectively, except that they use a  long  double
     argument number.  See ecvt(3) and gcvt(3).
