NAME
ecvt, fcvt - convert a floating-point number to a string.
SYNOPSIS
#include <stdlib.h>
char *ecvt(double number, size_t ndigits, int *decpt,
int *sign);
char *fcvt(double number, size_t ndigits, int *decpt,
int *sign);
DESCRIPTION
The ecvt() function converts number to a NULL terminated
string of ndigits digits, and returns a pointer to the string.
The string itself does not contain a decimal point; however, the position
of the decimal point relative to the start of the string is stored in
decpt. A negative value for decpt means that the decimal
point is to the left of the start of the string. If the sign of
number is negative, sign is set to a non-zero value, otherwise
it's set to 0.
The fcvt() function is identical to ecvt(), except that
ndigits specifies the number of digits after the decimal point.
RETURN VALUE
Both the ecvt() and fcvt() functions return a pointer to a
static string containing the ASCII representation of number.
The static string is overwritten by each call to ecvt() or
fcvt().
