 Note that the general negation operator provides for inequality testing. The
 two strings must take the form of optionally signed decimal integers,
-optionally followed by one of the letters &"K"& or &"M"& (in either upper or
-lower case), signifying multiplication by 1024 or 1024*1024, respectively.

 As a special case, the numerical value of an empty string is taken as
 zero.
