It was also done in the BBC Microcomputer's BASIC. The command EVAL() let
you enter a string comprising any mathematical function available on the
computer, (including established variables) and returned the result.

e.g.
A = 17: B = 42: C = EVAL("SQR(B - A)")

and C would be set to 5.

It looks like I'm gonna be around for a while..., :)
