**abs**Answer the absolute value of the receiver

**arcCos**Answer the arc cosine of the receiver

**arcCosh**Answer the hyperbolic arc-cosine of the receiver.

**arcSin**Answer the arc sine of the receiver

**arcSinh**Answer the hyperbolic arc-sine of the receiver.

**arcTan**Answer the arc tangent of the receiver

**arcTan: x**Answer the angle (measured counterclockwise) between (x, self) and a ray starting in (0, 0) and moving towards (1, 0) - i.e. 3 o’clock

**arcTanh**Answer the hyperbolic arc-tangent of the receiver.

**ceilingLog: radix**Answer (self log: radix) ceiling. Optimized to answer an integer.

**cos**Answer the cosine of the receiver

**cosh**Answer the hyperbolic cosine of the receiver.

**estimatedLog**Answer an estimate of (self abs floorLog: 10). This method should be overridden by subclasses, but Number’s implementation does not raise errors - simply, it gives a correct result, so it is slow.

**exp**Answer e raised to the receiver

**floorLog: radix**Answer (self log: radix) floor. Optimized to answer an integer.

**ln**Answer log base e of the receiver

**log**Answer log base 10 of the receiver

**log: aNumber**Answer log base aNumber of the receiver

**negated**Answer the negated of the receiver

**positiveDifference: aNumber**Answer the positive difference of the receiver and aNumber, that is self - aNumber if it is positive, 0 otherwise.

**raisedTo: aNumber**Return self raised to aNumber power

**raisedToInteger: anInteger**Return self raised to the anInteger-th power

**sin**Answer the sine of the receiver

**sinh**Answer the hyperbolic sine of the receiver.

**sqrt**Answer the square root of the receiver

**squared**Answer the square of the receiver

**tan**Answer the tangent of the receiver

**tanh**Answer the hyperbolic tangent of the receiver.

**withSignOf: aNumber**Answer the receiver, with its sign possibly changed to match that of aNumber.
