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.
