well, pd is not the only program, that has to handle string to float
conversions ... most parsers i know, would allow a leading '+' char for
parsing floats ...

maybe the newbie is confused by +1 being a symbol? or, if he's not
confused by +1 being a symbol, then probably by 1e+2, being a float ..

There's no such entity as "most people". These are generalities. All
generalities are meaningless. You've got to pin it down to a specific
person doing a specific thing at a specific time and space.
