BITWISE LOGICAL FUNCTIONS

THE BITWISE AND OF A LIST OF INTEGERS

With no arguments returns identity -1

• <expr> the integers
• returns the result of the and operation

With no arguments returns identity 0

• <expr> the integers
• returns the result of the inclusive or operation

With no arguments returns identity 0

• <expr> the integers
• returns the result of the exclusive or operation

• <expr> the integer
• returns the bitwise inversion of integer

Defined in common.lsp

• <expr1> the first integer
• <expr2> the second integer
• returns T if the result of the and operation is non-zero, else NIL

Part of math extension

• <expr1> integer to shift
• <expr2> number of bit positions to shift (positive is to left)
• returns shifted integer
