Section 2 Percentage and Calendar Functions 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. Percentages 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 Display 300 300. Keys in the base number. \ 300.00 Pressing \ separates the next number entered from the first number, just as when an ordinary arithmetic calculation is performed. 14 14. Keys in the percentage. b 42.00 Calculates the amount. 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. 26 File name: hp 12c_user's guide_English_HDPMBF12E44 Printered Date: 2005/7/29 Page: 26 of 209 Dimension: 14.8 cm x 21 cm
