  Depends on the application. Years ago (10?) I made a little 
interest calculating C program, floating point and rounding gave 
me so many issues with 1-2 pennies off that I went with an int 
and just took the bottom 2 digits as pennies. Worked far better 
than fighting with the floating point issues.

  I do remember somewhere that the double could be used to 
accurately calculate money up to 18 digits, but I can't remember 
if there was a specific mode you had to tell the FPU.
