(Less Than Or Equal) - HP 48gII Advanced User's Reference Manual

If one object is a symbolic (an algebraic or a name), and the other is a number or symbolic or
unit object, < returns a symbolic comparison expression that can be evaluated to return a test
result.
For real numbers and binary integers, "less than" means numerically smaller (1 is less than 2).
For real numbers, "less than" also means more negative (–2 is less than –1).
For strings, "less than" means alphabetically previous ("ABC" is less than "DEF"; "AAA" is less
than "AAB"; "A" is less than "AA"). In general, characters are ordered according to their
character codes. This means, for example, that "B" is less than "a", 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 +.

(Less than or Equal)

Type: Function
Description: Less Than or Equal Function: Tests whether one object is less than or equal to another object.
The function returns a true test result (1) if the first argument is less than or equal to the
second argument, or a false test result (0) otherwise. If one object is a symbolic (an algebraic or a
name), and the other is a number or symbolic or unit object, returns a symbolic comparison
expression that can be evaluated to return a test result.
For real numbers and binary integers, "less than or equal" means numerically equal or smaller (1
is less than 2). For real numbers, "less than or equal" also means equally or more negative (–2 is
less than –1). For strings, "less than or equal" means alphabetically equal or previous ("ABC" is
less than or equal to "DEF"; "AAA" is less than or equal to "AAB"; "A" is less than or equal to
"AA"). In general, characters are ordered according to their character codes. This means, for
example, that "B" is less than "a", 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 temperature and not differences in temperatures. For compound temperature units, the
calculator assumes temperature units represent temperature differences. For more information
