Ne:<>

One may wish to do conditional processing dependent upon whether two numerical expressions are unequal or not.  The form of the syntax that can be employed in such a case is

Terma ne Termb

or

Terma <> Termb

where ne or <> can be used interchangeably.  Examples from formconditional.gms

If(x ne 2, z=2);

Eq2$(x<>2)..  zz=e=3;

Loop(I$(sqrt(x) <> y+2),z=z+1)
