Fixnum

The class for the fixed range integers fit in the machine's pointer, which is 31 bits length on most machines. Fixnums are immediate values. If the result of the operations on fixnums exceed the range, it will automatically expanded to bignums.

SuperClass:

Integer

Methods:

self + other

self - other

self * other

self / other

self % other

self ** other

Arithmetic operations.

~ self

self | other

self & other

self ^ other

self << bits

self >> bits

Bit operations

id2name

Returns a corresponding strings to the number. If there is no corresponding symbol to the integer, it returns nil.

remainder(other)

Returns remainder of the numbers. In case either number is negative, the evaluated value differs from that of the operator %.

  13 %  4  =>  1
  13 % -4  => -3
 -13 %  4  =>  3
 -13 % -4  => -1

  13.remainder(4)    =>  1
  13.remainder(-4)   =>  1
(-13).remainder(4)   => -1
(-13).remainder(-4)  => -1
