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.
