Percentage Functions

The hp 12c platinum 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.

Percentages in RPN Mode

In RPN mode, to find the amount corresponding to a percentage of a number:

1.Key in the base number.

2.Press \.

3.Key in the percentage.

4.Press b.

For example, to find 14% of $300:

Keystrokes

Keys in the base number.

\

300.00

Pressing \separates the next

calculation is performed.

Keys in the percentage.

b

If the base number is already in the display as a result of a previous calculation, you should not press \ before keying in the percentage — just as in a chain arithmetic calculation.
