n output the absolute value of its input.
n output the arctangent of its input.
n output the cosine of its input.
n calculate the natural base e (2.71828. . .) raised to
the power specified by its input.
n output the integer portion of its input by removing
the decimal portion, if any. No rounding occurs.
