Alphabetical Listing of Operations

Operations whose names are not alphabetic (such as +, !, and >) are listed at the end
of this appendix, starting on page 900. Unless otherwise specified, all examples in
this section were performed in the default reset mode, and all variables are assumed
to be undefined. Additionally, due to formatting restraints, approximate results are
truncated at three decimal places (3.14159265359 is shown as 3.141...).

Returns the absolute value of the argument.
If the argument is a complex number, returns the
number's modulus.
Note: All undefined variables are treated as real
variables.

Compares two real integers bit-by-bit using an
operation. Internally, both integers are
and
converted to signed, 32-bit binary numbers.
When corresponding bits are compared, the result
is 1 if both bits are 1; otherwise, the result is 0.
The returned value represents the bit results, and
is displayed according to the
You can enter the integers in any number base.
For a binary or hexadecimal entry, you must use
the 0b or 0h prefix, respectively. Without a prefix,
integers are treated as decimal (base 10).
If you enter a decimal integer that is too large for
a signed, 32-bit binary form, a symmetric modulo
operation is used to bring the value into the
appropriate range.
