Thread: Need help: converting string to double

Hi, all. I do search the forum before raise my problem. I need to convert a string to a double, but the atof() or strtod() is not work. Why? What is wrong with my code?

Code:

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

int 
main (int argc, char *argv[])
{
	char *pr0 = "0.05";
	char *ptr;
	double pr2, pr3;
	pr2 = atof(pr0);
	pr3 = strtod(pr0, &ptr);
	printf("The number from atof()   is: %d\n", pr2);
	printf("The number from strtod() is: %d\n", pr3);
	return 0;     
}

Here is the output after compiled and run:

The number from atof() is: -1717986918
The number from strtod() is: -1717986918

Anyone can help?

Use %f in your prinf for a double, not %d that's for signed integers.

Thank you so much. It work now.
