After posting this, I noticed that my algorithm wasn't
rounding properly:

IDL> number = -2.343583743e-5
IDL> Print, Number_Formatter(number, DECIMALS=4)
-2.3435e-5

So I've just put up a new version that does this
correctly.

IDL> Print, Number_Formatter(number, DECIMALS=4)
-2.3436e-5

Cheers,

David
