Floating point - please enlighten me!

You could simplify your math to make it easier for the Picbasic commands.

Since you have:

Temp = ADC10 * ((ADC10 * .00034) + .2235)

Why don't we get rid of that ugly .00034
1/.00034 = 2941

So we multiply both sides by 2941 ...

Temp * 2941 = ADC10 * (ADC10 + 657)

Then lets divide both sides by 2941 ...

Temp = (ADC * (ADC10 + 657)) / 2941

Then you can use div32

dummy = ADC10 * (ADC10 + 657)
Temp = div32 2941

And I think the result is close enough...
