Hello Kimmo,

I'll have to look at both functions syntax in order to understand how
it works, but it works!

Thanks for that.

And I agree with Tom when he says that PHP has not been created for
that kind of work. Doing that in C, I used an union to reach
float/double's bits.

Thanks guys for your time.

Yannick
