Author: facundo.batista Date: Thu Aug 2 04:16:24 2007 New Revision: 56655 Added: python/branches/decimal-branch/Lib/test/decimaltestdata/squareroot_extra.decTest Log: New tests for squareroot, coordinate with Cowlishaw, maybe he'll keep this as a separated file or integrate these tests in the standard squareroot.decTest file in a later version. Thanks to Mark Dickinson.

In particular, these tests concentrate on +-- (1) cases where the input precision exceeds the context precision, and +-- (2) cases where the input exponent is outside the current context, +-- and in particular when the result is subnormal +-- +-- maxexponent and minexponent are set to 9 and -9 throughout these +-- cases; only the precision changes. The rounding also does not +-- change, and should be irrelevant. Ideally these tests could be +-- run with all rounding modes to check that the rounding mode does +-- not affect any of the results. + +version: 2.xx + +extended: 1 +rounding: down +maxexponent: 9
