≠ (Not equal)
Type: Function
Description: Not Equal Function: Tests if two objects are not equal.
The function ≠ returns a true result (1) if the two objects have different values, or a false result
(0) otherwise. (Lists and programs are considered to have the same values if the objects they
contain are identical.)
If one object is algebraic or a name, and the other is a number, a name, or algebraic, ≠ returns a
symbolic comparison expression that can be evaluated to return a test result.
If the imaginary part of a complex number is 0, it is ignored when the complex number is
compared to a real number, so, for example, 6 and (6,0) and considered to be equal.
For unit objects, the two objects must be dimensionally consistent and are converted to common
units for comparison. If you use simple temperature units, the calculator assumes the values
represent temperatures and not differences in temperatures. For compound temperature units,
the calculator assumes temperature units represent temperature differences. For more
information on using temperature units with arithmetic functions, refer to the entry for +.
Access: !Ä ( Äis the left-shift of the Wkey).
