commit 4c14ee3c96bdc74f8b7952205bcc64bc4b5ff5f4

    NEWS: added entry for new operator macros to gal_arithmetic
    
    I forgot to add a notice about these macros in the previous commit that
    these macros were added. I also noticed that the comments in
    'lib/gnuastro/arithmetic.h' for these operators wasn't too descriptive.
    
    With this commit both have been added.
