Square root in assembly

Hello,
How can I find a square root of a number in 1/256 decimal point percision? How can I write a subroutine that does that in assembly?

Hi, there are 2 ways: 1) Either the microprocessor has an instruction in its instruction set which performs that operation. (I think Pentium has an instruction like SQRT). 2) If the operation is not supported in H/W, then you should implement any numerical algorithm to find the square root of a number.

No point reinventing the wheel. There must be hundreds of asm code scraps out there.
Try Siomtel.

is all about the C++ arrays
There is no place like 127.0.0.1

You could always just compile the sqrt() function and take a look at the code generated..

Hello
Thank you all for your replies. Well, the whole square root thing is not about processors like Intel. Actually, I am trying to do it on Motorola ( Freescale ) HC12 which does not support such an instruction. I need to figure out how to calculate the fraction part only. It seems like pain in the butt to loop over and over again to devide a 32 bit number or something.
