double strtod(const char *nptr, char **endptr)
Description:
Header file:
Parameters:
Example:
Error conditions:
Remarks:
502
Return values:
Converts a number-representing string to a double type floating-point number.
<stdlib.h>
endptr
Normal:
nptr
#include <stdlib.h>
const char *nptr;
char **endptr;
double ret;
If the converted result overflows or underflows, ERANGE is set for errno.
According to section 10.1.3 (4), Floating-Point Specifications, the strtod
function converts data, from the first numeral or the decimal point up to the
character immediately before the character that does not represent a floating-
point number, into a double type floating-point number. However, if neither the
exponent nor decimal point is found in the data to be converted, it is assumed
that the decimal point comes next to the last numeral in the string. In the
address pointed by endptr, this function sets up a pointer to the first character
that does not compose a floating-point number. If some characters that do not
compose a floating-point number come before the first numeral, the value of
nptr is set in this address. If endptr is NULL, nothing is set in this address.
Abnormal:
ret=strtod(nptr, endptr);
If the converted data overflows: HUGE_VAL with the same sign
Pointer to the storage area containing a pointer to the first
If the string pointed by nptr is beginning with a character that
does not represent a floating-point number: 0
If the string pointed by nptr is beginning with a character that
represents a floating-point number: Converted data as a double
type floating-point number
as that of the string to be converted
If the converted data underflows: 0
Pointer to a number-representing string to be converted
character that does not represent a floating-point number
