Use of Kilo, Mega,Tera in Plus42

[Dave Britten]

If you just want something like Casio's engineering symbols (i.e. a different form of engineering display mode using alpha prefixes, with no attachment to any specific units), I wrote a program to do that a few years ago:

This allows doing all the same things you would on a Casio: entry and display of figures using engineering symbols (e.g. 2500k), and displaying a result converted to different symbol/mantissa (e.g. 2500k, 2.5M, 2500000, etc.).
