Returns the value of e (approximately
2.718) raised to the power n. The
returned value will
be in error if n lies outside the range tram -87 to
+88, since the result
will then exceed the numeric range of Easel
Returns the Integer value of the number, by truncating at the decimal
point. The truncation always operates towards smaller numbers. Thus;
i nt (3. 7J returns 3
int (-4.8) returns-5
Returns the natural,
or base e, logarithm of n. An error results if n is
negative or zero.
Returns the value of the mathematical constant

Returns + 1, -1, or 0, depending on whether the argument is positive,
negative or zero.
Returns the value of the Sine of the specified (radian) angle.
Returns the square root of the number
n, which must not be negative.
Returns the tangent of the specified (radian) angle.
