Thanks Rashakil.

I tried implementing it that way. We then had to compare the efficiency (number of iterations) of the BissectionSQRT method with that of another sqrt method. I tried...

Thanks for the reply indianscorpion.

The point being... the original code worked! Thanks DeepZ. Much appreciated.
