Description uffe 2014-04-25 07:22:18 UTC 
Switching base during calculation returns malformed expression

When switching base eg dec to hex or opposite during calculation it is impossible to use the converted result in further calculations with the new base - malformed expression error is returned

Hi there,

Can you provide an example to reproduce the bug? And the exact version of Calculator you're using?

Thank you.. :)

Using gnome-calculator 3.12.1 on ArchLinux

Start calculator

switch to decimal base

type in: 4+7 <enter>

result shown: 11 

switch to hex base

result shown: B

type in: + 3 (in addition to the existing shown 'B'

press enter

malformed expression is shown

Additional note.

I have pinned down the problem origin, but was unable to fix the issue. The problem is the iterators of tagged substring are getting reassigned to invalid indexes after call to TextBuffer.insert_with_tags (); from method reformat_ans (); in math-equation.vala.

Thank you for the bug report.

The issue has been fixed, and will be available with next release of calculator. :)
