Dear cygwin team,=20
I cannot correctly input floating point numbers via scanf. I am using =
gcc 2.95.3-4 as it is distributed by cygnus solutions. My machine is a =
Pentium Win98 computer. Please find attached the requested cygcheck.out =
file and below a code snip for the problem. I would be happy to get some =
ideas.=20
Regards, Marold
Command line:
$ gcc scanf_float.c
Source code:
#include <stdio.h>
int main(void)
{
int i;
float flt;
double dbl;
printf("Enter int: "); /* 55 */
scanf("%i", &i);
printf("i=3D%i\n", i); /* 55, ok */
=20
printf("Enter float: "); /* 5.543 */
scanf("%f", &flt);
printf("flt=3D%f\n", flt); /* 5543.000000, ERROR */
printf("Enter double: "); /* 5.543 */
scanf("%lf", &dbl);
printf("dbl=3D%f\n", dbl); /* 5543.000000, ERROR */
=20
return 0;
