[X4U] Tiger's Calculator.app no longer does percentages?

15% of 1 is 0.15, but to say "15%, by definition, is 15/100=0.15" is  
incomplete.
because that implies that 15% of ANY number is 15/100=0.15

the complete expression should be:  "15/100 * n"  where n is any  
number between -infinity and + infinity.

KoalaCalc does our calculation for us the way we intend it do: 28.05  
+ 15% = 32.2575

So, the difference between that or the Panther calc and the Tiger  
calc is the programming in of the understanding that the user wants  
15% OF the number already entered.

OK..it's now 3am..now, where is that leftover pumpkin pie I was  
after....
