[fpc-pascal] Parsing Smalltalk-style numbers

[Mark Morgan Lloyd]

Does anybody have any Pascal code to hand which will parse 
Smalltalk-style numbers, i.e. written with an explicit radix indicator?

For example, 8r34.1 (octal) parses to 28.125 (decimal) and 2r11e6 parses 
to 192 (examples from the Smalltalk "Blue Book").

I know it's not too difficult, I'm just trying to save myself a bit of 
work if possible.
