I am a common abstract superclass for all Integer implementations.
My implementation subclasses are SmallInteger, LargePositiveInteger, and LargeNegativeInteger.
See my Integer superclass for general numeric methods

Some common methods (many inherited from Integer)

arithmetic selectors:
- + - / *
- // (integer quotient) \\ (modulo)
- abs, negated, quo:, reciprocal, rem:
Comparing
- <, >, =
mathematical selectors
- sqrt, squared
- ln, log
- gcd, lcm, factorial, take: (combinations taken k at a time)
trigonometric selectors
- sin, cos, tan
- arcSin, arcCos, arcTan
- degreeCos, degreeSin
Truncation and rounding
- ceiling, floor
- roundTo:, roundUpTo:, rounded,
- truncateTo:, truncated
Testing
- odd, even, positive, negative, sign
- isNumber, isNaN, isZero, isDivisibleBy:
- isInteger, isPowerOfTwo
converting
- asNumber, asPoint, asCharacter, asHexDigit
- degreesToRadians, radiansToDegrees
- @ (special primative for points 1 @ 1)
Bit manipulation
- << nn, >> nn (bit shifting nn bits)
- bitOr: bitAnd:, bitXor:,bitClear:, bitInvert
- lowBit, highBit
Intervals (see Interval class)
- to:, to: by:, to: by: do:, to: do:
enumerating
- timesRepeat:
Printing
- printOn:, printStringBase:
- asStringWithCommas, asWords, romanString, radix:

Integer division consists of:
/ exact division, answers a fraction if result is not a whole integer
// answers an Integer, rounded towards negative infinity
\\ is modulo rounded towards negative infinity
quo: truncated division, rounded towards zero
