`strtod()`, `strtof()`, `strtold()` doesn't convert correctly hexadecimal value from string

[mateusz-bloch]

When the string to be converted by strtod(), strtof(), strtold() has a hexadecimal value, the conversion does not proceed correctly

• Code to reproduction:

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

int main (void)
{
    char str[] = "0X1.FFFFFEP-127";
    float strtof_output = strtof(str, NULL);
    double strtod_output = strtod(str, NULL);
    long double strtold_output = strtold(str, NULL);

    printf("%f\n", strtof_output);
    printf("%lf\n", strtod_output);
    printf("%Lf\n", strtold_output);

    return 0;
}
