Module (chicken bitwise)
Binary integer operations are provided by the (chicken bitwise) module.
Binary integer operations
- bitwise-and N1 ...procedure
- bitwise-ior N1 ...procedure
- bitwise-xor N1 ...procedure
- bitwise-not Nprocedure
- arithmetic-shift N1 N2procedure
Binary integer operations. arithmetic-shift shifts the argument N1 by N2 bits to the left. If N2 is negative, then N1 is shifted to the right. These operations only accept exact integers.
bit->boolean
- bit->boolean N INDEXprocedure
Returns #t if the bit at the position INDEX in the integer N is set, or #f otherwise. The rightmost/least-significant bit is bit 0.
integer-length
- integer-length Nprocedure
Returns the number of bits needed to represent the exact integer N in 2's complement notation.
