ecvt
Converts a floating-point number to a string.
Syntax
char *ecvt (double value, int ndigit, int *decpt, int sign);
Parameters
value The floating-point number to be converted to a character
string.
ndigit The number of digits to convert.
decpt A pointer to an integer to which the position of the
decimal point relative to the beginning of the string is
returned.
sign A pointer to an integer to which a flag indicating the sign
of the number is returned.
Return Values
x A pointer to a character array containing the results of
the conversion.
Description
The ecvt function converts value to a null-terminated string of ndigit
digits and returns a pointer to the string. The resulting numeric string
is rounded and left-justified without leading zeros. 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). The decimal point is not included in the returned string. If
the sign of the result is negative, the word pointed to by sign is
non-zero. Otherwise, the word pointed to by sign is zero.
The values returned by ecvt() point to a single static data array whose
content is overwritten by each call.
