The !MFCalc Software Application is a Multi Function Scientific Calculator for the Acorn RISC OS Wimp environment, and is available for free download.

After having downloaded and unzipped the !MFCalc Application, drag the application to a suitable directory on your hard disc. Double click on the !MFCalc icon to load it onto the icon bar.

Clicking on the bar icon brings up the main 'SetUp' panel.

Select options and/or type a Calculation into the Input: slot on the 'SetUp' panel and then click on the 'Calculate' icon. !MFCalc then returns the answer, or a message indicating what it has done.

Additional Help is available from the bar icon menu, or by using the Acorn facility !Help, present in the 'Apps' directory.

Version 4.00 admitted of binary input e.g. %101 is decimal 5, and the assignment operators:- '+=', '-=', '*=' and '/=' e.g. a%+=1 adds 1 to the value held by a%.

Version 5.00 admitted of inverse (arc) hyperbolic functions, and the operators:- '++' and '--' e.g. a%++ returns the current value of a%, but adds 1 to the value stored in a%.

Version 6.00 now allows the separation of multiple assignments by any series of colons or semi-colons. Also, you may use single variable names with '++', or '--', so long as it's not the first assignment.

Read the 'ReadMe1st' file present in the zipped file for more information, and the '!ReadMe' file within the !MFCalc application (double click over the application icon with 'Shift' held down to find it), for conditions of use.
