What I meant is that I first overlooked 'e' and '+' as valid characters
that can appear together within a string to be converted to a float.
The following compiles and works as expected:
var x : real;
begin
val ('4.1e+5', x); // "e+" is valid for val (within context)
writeln (x);
end.
The point I was making was that if someone is going to make a floating
point mask (note the subject...) that one should be careful not to
exclude any valid characters if restricting input by character. I'm not
sure if the set I suggested ['-', '.', '0'..'9', 'e', 'E', '+'] is
complete.
Cheers,
~David.
