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

[Doug McNutt]

Boss:  I'm sorry but business has been bad this month. I'm going to 
cut your salary by 50%.

Employee:  Gee, that will be tough at Christmas time.

Boss: I'm going to make it all up with a 50% increase in January.

*****
So I buy it for $5 and I sell it for $10. Surely it's OK to advertise 
a 50% markup. 50% of $10 is what I paid for it, isn't it?

*****
This survey has a 3% probability of error. SQRT(1000)/1000 = 3% 
ignoring everything about selecting the sample.

*****
The moral is that it's not only calculators that abuse the English 
grammar of "%".

--> If you are presented a number as a percentage, and you do not 
clearly understand the numerator and the denominator involved, you 
are surely being lied to. <--
