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

yeah..we get that concept. 0.15 of anything you apply it to, and you  
thereby prove our case: we are applying the % function TO 28.05, not  
to 1.0!

what appears to be broken in the calculator is the understanding of  
what to DO with that fact in an algebraic expression.

I guess there are 2 sides here, and "our" side feels that to say  
"28.05+15% = 28.2" is sheer idiocy from any angle, the flaw being  
that Calculator either merely converts the number 15 to a decimal  
percent equivalent, OR Calculator assumes that you want to add 15% of  
1.0.

Either case is logically incorrect. Again, we are not disputing that  
15% of 1 is 0.15.

I'm old enough to remember a time when it was a huge selling point  
for a calculator to have Algebraic logic built-in. Without that,  
you're stuck with busting out the hierarchy of operations,  
calculating each result, then adding the results together, which  
almost completely makes the calculator worthless.
