NAME

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

SYNOPSIS

13       char *qfcvt(long double number, int ndigits, int *decpt, int *sign);
14
15       char *qgcvt(long double number, int ndigit, char *buf);

DESCRIPTION

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