Percentage Functions
The hp 12c includes three keys for solving percentage problems: b, à, and Z.
You don’t need to convert percentages to their decimal equivalents; this is done
automatically when you press any of these keys. Thus, 4% need not be changed to
0.04; you key it in the way you see and say it: 4b.
