HP 50g Graphing, 48gII Graphing manual ≠ Not equal, Description

example, that “a” is greater than or equal to “B”, since “B” is character code 66, and “a” is character code 97.

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 +.

≠(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 +.
