Article contents:[[tags: manual]] [[toc:]] == Module (chicken bitwise) Binary integer operations are provided by the {{(chicken bitwise)}} module. === Binary integer operations <procedure>(bitwise-and N1 ...)</procedure> <procedure>(bitwise-ior N1 ...)</procedure> <procedure>(bitwise-xor N1 ...)</procedure> <procedure>(bitwise-not N)</procedure> <procedure>(arithmetic-shift N1 N2)</procedure> 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 <procedure>(bit->boolean N INDEX)</procedure> 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 <procedure>(integer-length N)</procedure> Returns the number of bits needed to represent the exact integer N in 2's complement notation. --- Previous: [[Module (chicken base)]] Next: [[Module (chicken blob)]] Description of your changes:
