Floating point diveded by 2

[Jan Lichtenbelt]

Is it possible to divide a floating point variable A by 2 in the following way?

A>>1

Or must it be done by a floating point division


Kind regards

Hi Jan,

I'm not too sure about this one. I have a feeling it won't work but why not give it a go on the hardware and let us know your results. It certainly won't hurt anything.

OK, You are right. I could check it myself. Here are the results

A is a floating point variable, in my example 4.321

respectively: A>>1 , A/2 , fdiv(A,2)
Simulation: 2.000000 2.160500 2.160500
PIC-Hardware: 0.000000 0.000000 2.160500

So the only correct way is using the fdiv() function

Hi Jan,

Thanks for letting us know. I had a feeling it wouldn't be that simple but glad you tested it to be sure.
