Michael Sevakis	66b49dc0b2	Need limits.h for hosted builds ... Change-Id: Iac1433957de80ad5db51396f74acf1f4f8d45bf3	2017-10-01 23:27:41 -04:00
Michael Sevakis	b2a373eb64	Replace fp_sqrt function with one that only uses shift, or and sub. ... Simply extends the current isqrt() to be able to do fractional bits and improves the initial estimate using clz(). iqrt() itself is no more and is equivalent to fp_sqrt(x, 0). The original also had a small bug where the guess comparision should have been >=, not >. Uses no large integer math or division and is very accurate (simply returns a truncated fraction).
