Hello, Is there an operator/function in band math that will allow me to round up to a particular decimal place? The file in question is a Rapideye ToA reflectance image. I'd ideally like to get it to 3 decimal places so eventually I could multiply the image by 1000 (to save disc space). Any help would be much appreciated. Many thanks, James.

There is no specific routine in IDL or ENVI to do this but there are some discussions on the IDL newsgroup on how it can be accomplished. Here are a couple of examples: https://groups.google.com/forum/#!top... http://objectmix.com/idl-pvwave/16884...

Thanks for the reply. However, my license server doesn't allow me to use IDL. I opted for a work around to get my desired result using band math within ENVI. uint(round (b1 * 1000)) James
