1.92.4 Integer: bit operators

allMask: anInteger

True if all 1 bits in anInteger are 1 in the receiver

anyMask: anInteger

True if any 1 bits in anInteger are 1 in the receiver

bitAt: index

Answer the index-th bit of the receiver (the LSB has an index of 1)

bitAt: index put: value

Answer an integer which is identical to the receiver, possibly with the exception of the index-th bit of the receiver (the LSB having an index of 1), which assumes a value equal to the low-order bit of the second parameter.

bitClear: aMask

Answer an Integer equal to the receiver, except that all the bits that are set in aMask are cleared.

bitInvert

Return the 1’s complement of the bits of the receiver

clearBit: index

Clear the index-th bit of the receiver and answer a new Integer

digitAt: index

Answer the index-th base-256 digit of the receiver (byte), expressed in two’s complement

highBit

Return the index of the highest order 1 bit of the receiver.

isBitSet: index

Answer whether the index-th bit of the receiver is set

lowBit

Return the index of the lowest order 1 bit of the receiver.

noMask: anInteger

Answer true if no 1 bits in anInteger are 1 in the receiver.

setBit: index

Set the index-th bit of the receiver and answer a new Integer
