in reply to A PerlQt Calculator

Cool! I gotta learn more about Qt now. I did have problems installing Qt from via perl -MCPAN -eshell but was able to get it installed from by following the links you provided. I did have a problem doing 2 X 2 = ? But I really like your PerlQt Calc. ++

    Oops, good catch. That was my mistake. The display was filtering out results with only one digit.

    changing the filter fixes that. 

    
$result =~ /^-?\d+\.?\d+$/ 

to

$result =~ /^-?\d+\.?\d*?$/
