Square Root of any Number
Find the nearest square root ( s ) below radicand ( r ) and apply to equation
+sqrt%28+r+%29+ = +s+%2B+%28r+-+s%5E2%29+%2A+%281%2F%28%28s+%2B+1%29%5E2+-+s%5E2%29%29+


Example: +sqrt%28+54+%29+ = 7 + ((54 - 49) * 1/(64 - 49)) = 7.333


Our Est Sqrt = 7.333
Actual Sqrt = 7.348


Will square root any number, including decimals, accuracy is within a few thousandths.
It will NOT work for radicands below 4
