How Many Bytes Does Float Occupy Inside PIC Microcontroller?

    1. The problem statement, all variables and given/known data

    How many bytes does a variable of float data type occupy in the data memory of PIC microcontroller?



    2. Relevant equations

    None


    3. The attempt at a solution

    All I know, is that float data type has a size of 4 bytes, that's 32 bits. I'm not sure if it occupies the same size inside the data memory of the PIC.

    There are many different kinds of PIC controllers, ranging from 12-bit, 13-bit, 14-bit, 16-bit, up to 32-bit wide code memory.

    I looked at this wikipedia article, and didn't see any mention of floating point op codes, so perhaps floating point operations are done in a kind of fixed-point technique.

    I don't have any experience with PIC microcontrollers - most of my assembly experience has been with various Intel x86 chips and some with Motorola 68000 family.
