Yes and no, PBP have it's limit... it's not something new. But decent math approach would save the day.
To make a short story, PBP works with integer, nowhere in the manual you'll find an answer about floating points and or square power.
Thinking never killed... sure you use the easy route... but...
i think few people may need to relax or simply be ban out of here...

It's not a bug, it's a random feature.
There's no problem, only learning opportunities.

just a little bit of brain work ...
Hi, Steve
Why not change the formula to :
16 x 115 / 4 x ( 200 - SQR ( 36 000 )) = 5 000 ( exactly 4721. .... ! PbP will return 5060 here ... )
PbP would do that without any pain ... but not very precisely, as you see !!!
Alain
Ok, ... also just look for possible overflows !!!

Why insist on using 32 Bits when you're not even able to deal with the first 8 ones ??? ehhhhhh ...
************************************************** ***********************
IF there is the word "Problem" in your question ...
certainly the answer is " RTFM " or " RTFDataSheet " !!!

Oh boy looks like I got over eager with another project, well I will see what I can do to get some sort of formula working in PBP.
Looks like I will be doing alot of debug and lcdout on this one.

Don't forget about the floating point math routine package that Microchip has (and are at the MeLabs site). Those subroutines will handle the math that PBP won't...but you'll have to learn how to interface with them...

just curious ...
Hi, Tico
I'm curious to see where your formula came out ... and what used for.
looks too much like a triangle solving and inch converting !!!

PS ... see also here for math ... http://www.micromegacorp.com/pbp.html
a V3 chip is also available ... don't hesitate to browse !!! http://www.micromegacorp.com/umfpu-v3.html

The formula divides a circle into sections that have an equal area.
Didnt have a chance to work on any code today got called out to the field.
Will work on some possibly over the weekend if not I will on monday.

There's still the huge LOOKUP table + interpolation method, but, not sure that i saw the real maths here or if i'm just brainless today... or both
