I am trying to make a program that will
find the sqaure root of any number. I have
ing a lot of trouble. Maybe it would help if
someone could show me the derivation
of the sqarue root mathematicaly.
please help,

still, im trying to find a way to extract an exact square root.
unless the only way is to use limits and see what number the
answer is closing in on, but then I would really be lost as far
as programming calculus theories.
There is solutions that will never be exact>>>sqrt(3,2);<<<<will never be exact. So as fare as I know there is no way you can write a program that can extract an exact square root of any number. You can use the theory from prev post and run it until it is good enough

i thought the same thing but then i remembered that
the default calculator that comes with windows can
calculate exact square roots.
I have to either right a program that can calculate square roots or absolute value, though if I can get the square root part down, i can use that for absolute value. Hopefully some can either assure there is no way or point me in the right direction of the right way.
The windows calc probably just uses QWORDS and uses the FSQRT instruction to get the square root.
With the FPU, no need to code an integer sqrt function or a floating point sqrt function. The days of floating point emulation ended with the FPU.
