[TxMt] Math.tmbundle Suggestion: overwrite previous results

[Timothy Bates]

CURRENT SITUATION: "Evaluate Line / Selection" barfs on lines like this
   25/10 = 2.5

PROBLEM: This means the user has to manually delete the "= nnnnn" if  
they wish to reevaluate the line

SUGGESTION: change the command to overwrite "( = [-0-9\.]+)" with the  
new result.

I don't speak perl, but this is the bit that would like changing

printf " = %s" `{ tr -d ,; echo; } | bc -l`| perl -pe 's/(\.[^0]+)0+$| 
\.0+$/$1/'

Bit early for xmas, but it would be great if a currency- and  
formatting-friendly command was available, i.e., one which would be  
happy to take

$250,000*12.5%

see "250000*12.5"

and return "$250,000*12.5% = $3,125,000"
