That seems bizzare. A test of strtod() might be in order. Attached is
a small program for running strtod.

Relativism is the triumph of authority over truth, convention over justice.
/* A simple test of strtod */
#include <stdlib.h>
#include <stdio.h>
main(void)
{
double d;
char line[128];
char *rest;
while((fgets(line, 128, stdin)) != NULL) {
printf("String retrived (%s)\n", line);
d = strtod(line, &rest);
printf("d == %lf\n", d);
printf("rest is (%s)\n", rest);
}
exit (0);
}
