Thanks for your help, Melanie. But I am using MPlab compiler.
I have another 6 question with MPlab assembler programming.
1. Is the PIC can use to check the value whether it is a positive or negative value?
2. Is the IF/ELSE statement available in MPlab?
3. How to compare and get the smallest number between three number?
4. After I use the fixed point division of the application note, AN617 in microchip, but the output is in floating point, then how to read the result?
5. If the maximum number of floating point is 0.125 in decimal number, then how many bits should I use for math operation?
6. In application note, AN575 in microchip, it said that floating point 0X823C5198, but how to read it? What decimal value is it?
