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

[net kat]

well, 0.15 is 15% of 1.0, not of 28.05, so the result of 28.2 is  
incorrect.

He isn't saying "28.05 + 0.15"  He IS saying "28.05 + 15% OF 28.05"

the Tiger calculator is, IMHO, misinterpreting our use of the % key  
in the calc. if you do
"100 + 15%," the Tiger calculator gives you "100.15" which ain't right.

The tiger calculator 'assumes' you want to add 15% OF 1 to the first  
number, which is idiotic. Why should the calculator assume you're  
wanting to add 15% OF 1?

Put in people language, this is what we want: "Calculator: here's my  
original number. Calculate 15% OF that number, add the two together,  
give me the result."

Yeah, we all know that we could do this:  "28.05 * 0.15 M+" Then "MR  
+ 28.05 ="   or we could do
"28.05 + (28.05*0.15)"

But why should WE be 'forced' to do the algebraic operation when we  
have a calculator which should do it for us?
