The calculator utility may be used for making mathematical
calculations involving numbers, including workspace variables such as the
dimensions of the image. The calculator uses natural input method, which makes input very easy to use and understand. It also displays its interpretation of the user’s input so that ambiguities and errors can be recognized immediately.
In addition to constants such as "pi", eight storage variable are
provided - A, B, C, D, E, F, X and Y. These are shared and persistent, i.e. they have the same
value across all calculation contexts within an instance of Chasys Draw IES Artist, including automatic calculation when entering number, and they maintain their values until that instance of Chasys Darw IES Artist is closed.
