Convert Integers: Decimal to Any Base
Below are two programs that allow conversion of integers from decimal to any designated base. Integers used in base other than 10 are presented in list format. Each digit is separate and listed in order of descending place value.
For example: To input 1282_9 (base 9), enter {1, 2, 8, 2} and designate 9 as the base. Digits are shown in numerical form and not in alphabetic. Hence, if you were working for hexadecimal, enter 10 for A, 11 for B, and so on. HP Prime Program DEC2BASE Code: EXPORT DEC2BASE(N,B) Convert 1254 to base 6. Result: {5, 4, 5, 0} (5450_6). (5 * 6^3 + 4 * 6^2 + 5*6) Convert 17291 to base 13. Result: {7, 11, 4, 1} (7B41_13) (7 * 13^3 + 11 * 13^2 + 4 * 13 + 1) HP Prime Program BASE2DEC Code: EXPORT BASE2DEC(L1,B) Convert 4281_9 to decimal (4 * 8^3 + 2 * 9^2 + 8 * 9 + 1) Input: {4, 8, 2, 1}, Base: 9 Result: 3583 Convert C107_16 to decimal (12 * 16^3 + 1 * 16^2 + 7) Input: {12, 1, 0, 7}, Base: 16 Result: 49415 |
