v-man i would recommend you to ditch bisection and use the tangent method to calculate square roots (and generally zeroes of derivable functions)
here's an implementation
it's MUCH faster (MUCH!)
this calcolates sqrt up to the maximun precision allowed
also this is not recursive so it's another advantage my implementation has.
