Float2Fract and Fract2Float sillyness

Hi there.

I am getting some strange behaviour from Float2Fract and Fract2Float.



The only successful tests were 1, 3 and 5. In the first, (Fract2Float), a float is passed to the function (which I would assume it would want a fractional type passed to it) and returns a float. The returned value is scaled between -1 and 1 from -32768 and 32767 (This would make more sense if this function was Float2Fract???)

In the third, I passed Float2Fract a float value in the normal float range and it gave me a fractional back with the value of 32767 (max. float value, I thought a fractional type could only be between -1 and + 0.9999???)

In the fifth, I passed Float2Fract a float value of 0.45806885 which came back as fractional 15010, which is the correct scale up of the first test.

I am confused and I must be doing something stupid! Please enlighten me about floats, fracts and what should be going in and coming out of these functions

Thanks a lot
