Absolute and Signum Functions
You can use the calculator to determine the absolute value and signum function of a number.
Absolute Values
Selecting { ABS } from the NUMBER FUNCTIONS menu changes the number in the display to its absolute value.Example
Calculate | 3 ÷ 10 - 2 | × 11.Procedure | Press | Display |
---|---|---|
Clear display | [ CLEAR ] | |
Perform the calculation. | [ ( ] 3 [ ÷ ] 10 [ - ] 2 [ ) ] | |
Calculate the absolute value | [ NUM ] { --> } { ABS } | |
Multiply the absolute value by 11. | [ × ] 11 [ = ] |
Signum Function
Selecting { SGN } from the NUMBER FUNCTIONS menu determines the sign of the number in the display and results in either a 1 or -1, depending on the sign. If the value in the display is 0 or greater, the result of the signum function is 1. If the value in the display is less than 0, the result of the signum function is -1.For example, if the display contains -0.941863 and you press [ NUM ] { --> } { SGN }, the calculator displays -1.
