comment What is a bit-shifting standard C function for calculating $f(x) = \frac{(2^{16}- 1)}{(2^{32} - 1)}\cdot x$
I'm writing a driver for the PIC32MX family, and I'm allowed to use specific bit lengths. Also, I just resorted to the division operator, but I learned a lot making this post. And if it should not work right, I'll come back and refer to these answers. Not only am I allowed, but I have to know the size of my types, I'm writing a freakin driver for and only for a family of 32-bit MCUs!

I don't think any of the above comments are correct. Making answer now...

I need an unsigned short, see post.

@Oleg567 that's casting, not scaling

@AndréNicolas thanks. Where did you read that? And is it an iff condition?

comment Explain a linear function property?
Do you mean "Why does it hold for the second inequality"? Since the second inequality, $y \lt 0$, is part of a sufficient condition not a consequence.

$1 - 0.\bar{9} = 0.00000\dots000\dots $ (you never get to $\dots0001.$).
