ECVT(3) Linux Programmer's Manual ECVT(3)
NAME
ecvt, fcvt - convert a floating-point number to a string.
SYNOPSIS
#include <stdlib.h>
char *ecvt(double number, int ndigits, int *decpt, int *sign);
char *fcvt(double number, int ndigits, int *decpt, int *sign);
DESCRIPTION
The ecvt() function converts number to a null-terminated string of ndigits digits (where ndigits is reduced to an system-specific limit
determined by the precision of a double), and returns a pointer to the string. The high-order digit is nonzero, unless number is zero. The
low order digit is rounded. 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. If number is zero, it is unspecified
whether *decpt is 0 or 1.
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().
NOTES
These functions are obsolete. Instead, sprintf() is recommended. Linux libc4 and libc5 specified the type of ndigits as size_t. Not all
locales use a point as the radix character (`decimal point').
