[gdal-dev] gdal raster calc - a modulo operator (%)?

Greetings!

I've been unable to find a modulo operator in CLI calc. It's not in the 
muparser functions or appear to be in the forth-coming 3.12 C pixel 
functions.

This has been working with muparser, but it's messy every time you need 
a simple modulo. pixel is real or int, div is int:

rint(pixel) - (rint(rint(pixel) / div) * div)

Am I missing something? If not, consider this a feature request! :)

Thanks!
Scott
