A more intelligent SDIFF

Hi all

I have two files which are essentially the same. However the way an exponent is written is different (i.e. in 1 file, a particular number might be written as 1.43230000E+02 whereas in another it might be 1.4323E2).

If I use SDIFF then the program will merely check the ASCII characters and not recognise the numbers are still the same.

Does anyone know of another program or another method (perhaps a script) that could be able to determine the differences?

Thanks,

Robbie
