kVariables

This calculator comes with 28 variables as standard. You can use variables to store values to be used inside of calculations. Variables are identified by single- letter names, which are made up of the 26 letters of the alphabet, plus r and θ. The maximum size of values that you can assign to variables is 15 digits for the mantissa and 2 digits for the exponent. Variable contents are retained even when you turn power off.
