    float
    double
    long double

    here is small program for you
    #include <stdio.h>

int main()
{
    float f;
    double d;
    long double ld;

    printf (
        "float       : %4d bytes\n"
        "double      : %4d bytes\n"
        "long double : %4d bytes\n"
        ,
        sizeof(float),
        sizeof(double),
        sizeof(long double)
    );    
    return 0;
}

    Am I right in saying that a double must have a decimal point where as a float is floating point so doesn't?
