ViewTools roundTo accuracy
Hello,
I recently had an issue using the roundTo method on some financial
figures. Results were sometimes out by one or two pence (it was a
cumulative effect).
Looking at the MathTool source code (ViewTools version 1.2), I can't
see any problem. However, writing my own wrapper around Java's
BigDecimal round method solved my problem. It may or may not be
deemed appropriate to use this in MathTool, I'm just saying it worked
for me. Haven't got any test cases I'm afraid.
Regards

Hi.
This problem should have been corrected in the latest subversion
revision (1.4-dev).
