How to calculate integer square roots
Submitted By: WEBMASTER
The purpose of this exercise was to create an algorithm to find integer square roots using only integer operations (this method was initially devised by me in 1990 - when I was 16 - for the ZX Spectrum +3 which had a Zilog Z80 (Intel APX 8080 compatible) processor which doesn't even have multiply or divide assembly instructions!).
