CVSROOT: /cvs
Module name: src
Changes by: ottocvs.openbsd.org 2004/12/01 01:29:38
Modified files:
usr.bin/dc : bcode.c
Log message:
Fix stop condition for sqrt. Due to the fact that we're doing Newton
iteration with intgeres, the stop condition is reached if x_n == x_n+1, or
the difference is one, but only stop if that is hit a second time. Avoids
looping with difference 1,-1,1,-1... Problem spotted by Paul de Weerd.
Regress tested against 4.2BSD dc(1) and GNU dc(1).
