Why can't PIC's support fp math

[jheissjr]

I guess it would always make a good project, interfacing a calculator to a PIC

Darrel Taylor,
I left a message in your interrupt thread under Code Examples about using your code for 18F's. Can you check it out and see what you think.

Hi,
Rememder as well that intel used to have to put FP for the 86xxx series in a separate "maths co-processor" chip that typically cost more than the main processor (I remember the £200 86287). And they still got bugs in them.
Don't forget that you can get an external math chip to go with your pic if you really need it.
As Bruce says, you don't really need FP for most microcontroller projects. When working with ADC's little thought on signal and Vref values in relation to the number of bit's and the real world value you are measuring can make the math much easier.

Hi Darrel,

I've been reading out most of your threads You're of no doudt endowed with programming talents I am curious, has it ever crossed your mind authoring a book?

sometimes i suspect he's the guy in the expression Taylor series

Hey that's a good Book title 'PIC programming... the Taylor series'

One thing that would make the lack of floating point less of an issue is if PBP fully supported 24 or 32 bit integer math.

For me, one of the worst parts of designing things is, having to write an Operators Manual for it when it's done.

I can't even fathom writing a whole book that I didn't have to, or be fired.

Nope, I'll leave that stuff up to Bruce.

But thanks for the thought.


Charles,
Yeah, wouldn't that be nice. Maybe even 64-bit?
