ECVT(S) XENIX System V ECVT(S)
Name
ecvt, fcvt, gcvt - Performs output conversions.
Syntax
char *ecvt (value, ndigit, decpt, sign)
double value;
int ndigit, *decpt, *sign;
char *fcvt (value, ndigit, decpt, sign)
double value;
int ndigit, *decpt, *sign;
char *gcvt (value, ndigit, buf)
double value;
int ndigit;
char *buf;
Description
ecvt converts the value to a null-terminated string of
ndigit ASCII digits and returns a pointer to the string.
The position of the decimal point relative to the beginning
of the string is stored indirectly through decpt (negative
means to the left of the returned digits). If the sign of
the result is negative, the word pointed to by sign is
nonzero, otherwise it is zero. The low-order digit is
rounded.
fcvt is identical to ecvt, except that the correct digit has
been rounded for FORTRAN F format output of the number of
digits specified by ndigits.
gcvt converts the value to a null-terminated ASCII string in
buf and returns a pointer to buf. It attempts to produce
ndigit significant digits in FORTRAN F format if possible,
otherwise E format, ready for printing. Trailing zeros may
be suppressed.

Notes
The return values point to static data whose content is
overwritten by each call.
