Bug in Apple's Calculator App? (Off topic)

I occasionally use the Calculator app for development work - nice hex / ascii / unicode display features, etc.

BUT, I was just exploring numerical accuracy with large numbers and hit a bug...

Type in 100 and click 10^x button. Result is  1e+100
Type in 150 and click 10^x button. Result is 1.84467440737e+146
Type in 160 and click 10^x button. Result is 1.84467440737e+146
Type in 200 and click 10^x button. Result is  1e+200

But taking log of the apparently incorrect results returns the correct values (150 and 160).
So something's going wrong with the display of large numerical values.


Sorry for off-topic post, but I know there are some Apple developers listening.
