Binary bounding operators are defined for
scalars (both real and
arrays (both real and complex). They restrict their
operands to a range of values. The following two operators are
x < y returns the smaller (i.e. closer to -Infinity, for
real numbers) of
x > y returns the larger (i.e. closer to +Infinity, for real
Comparison of complex numbers is based on their projection on 1+i; see Complex Numbers.
So, to restrict all elements of an array
x to between the values
of 20 and 33, use
x > 20 < 33.
