Re: [wxperl-users] Wx::wxVERSION and locale clash

[Mark D. <mar...@zn...>]

Hi,

I am guilty of using

if( Wx::wxVERSION() lt '2.006003') { ... }

in my code.
It started off as a reaction to:

Wx::wxVERSION() < 2.006003

returning true when the wxWidgets version was in fact 2.6.3

This is a problem with floating point numbers, I believe.

One soluition I will start to use with the current implementation, if my question is "is wxWidgets less than 2.6.3", is to do

if( Wx::wxVERSION() < 2.0060025) { ... }

It's ugly but it will work for numeric comparison and should therefore be locale independent.

That would seem a good idea going forward.
