Nicolas Cellier uploaded a new version of Kernel to project The Trunk: http://source.squeak.org/trunk/Kernel-nice.843.mcz ==================== Summary ==================== Name: Kernel-nice.843 Author: nice Time: 21 March 2014, 6:28:55.456 pm UUID: 28ea5418-9be7-964b-b0c1-fde1bf8528a3 Ancestors: Kernel-nice.842 Correct the bug I introduced for large integer sqrtFloor. If receiver was of the form 2^2n*u we did answer 2^n *E(sqrt(u)) But sqrt(u) = E(sqrt(u)) + residue where 0<=residue<1 And result is rather E(2^n*sqrt(u)) = E( 2^n*(E(sqrt(u)) + residue)) = 2^n*E(sqrt(u)) + E(2^n*residue) As 2^n * residue can be big (superior to 1), we miss the correct value by default. If we want to correct this, an approximation of residue is (u-E(sqrt(u))^2) / 2 E(sqrt(u)) This is more or less like super Newton-Raphson inner loop... It would be possible to duplicate super work, but I feel like it's adding too much complexity for small reward, so I prefer to remove offending code for now =============== Diff against Kernel-nice.842 =============== Item was removed: - ----- Method: LargePositiveInteger>>sqrtFloor (in category 'mathematical functions') ----- - sqrtFloor - "Return the integer part of the square root of self" - - | powerOfTwo | - (powerOfTwo := self lowBit - 1 // 2) > 1 - ifFalse: [^super sqrtFloor]. - ^(self bitShift: -2 * powerOfTwo) sqrtFloor bitShift: powerOfTwo!
