Re: [Jscheme-user] bug in string->number

[Ken A. <kan...@bb...>]

Hi Johathan,

What's happening here is that one of the JScheme extensions is to allow the use of Java syntax for numbers.  You can turn it off with:
> (set! U.useJavaSyntax$ #f)
#t
> (string->number "01438")
1438

Because of the leading "0" JScheme attempts to read the string in octal.
Because of the "8" an exception is thrown.  Our code catches the exception and simply tries to read the string as a float, which succeeds.  Clearly it should throw an error, which might have at least given you a hint.  I'll work to Tim to clean this up, thanks.
