C and F Hexadecimal

[-MFra-]

In the use of hexadecimal numbering, Mathcad gives an error when I use the hexadecimal number C, which is normally a unit of measurement and also for c which is the speed of light, the same for F. What should I do to avoid falling into error ?

Try prefixing the expression with 0 (zero), eg 0Ch

It has nothing to do with C being a unit. Numbers (even hex numbers) must begin with a decimal digit.

So x:=0Ch should do the job.

If you type x:=0Ch you will get an implicit multiplication symbol between 0 and C which you have to delete. Alternatively you may add the 0 only after typing Ch.

EDIT: I see, that Stuart has beaten me by four minutes 🙂

BTW, here is the appropriate text of the help system:

I haven't dealt with the topic for years and this is the result!
