Bit::ShiftReg Description

Bit Shift Registers with Rotate / Shift Operations Bit::ShiftReg is a Perl module that implements rotate left, rotate right, shift left and shift right operations with carry flag for all C integer types.SYNOPSIS * use Bit::ShiftReg qw( bits_of_byte bits_of_short bits_of_int bits_of_long LSB_byte MSB_byte LSB_short MSB_short LSB_int MSB_int LSB_long MSB_long ROL_byte ROR_byte SHL_byte SHR_byte ROL_short ROR_short SHL_short SHR_short ROL_int ROR_int SHL_int SHR_int ROL_long ROR_long SHL_long SHR_long ); imports all (or some, by leaving some out) of the available operations and functions * use Bit::ShiftReg qw(:all); imports all available operations and functions * $version = Bit::ShiftReg::Version(); returns the module's version number * $bits = bits_of_byte(); returns the number of bits in a byte (unsigned char) on your machine * $bits = bits_of_short(); returns the number of bits in an unsigned short on your machine * $bits = bits_of_int(); returns the number of bits in an unsigned int on your machine * $bits = bits_of_long(); returns the number of bits in an unsigned long on your machine * $lsb = LSB_byte($value); returns the least significant bit (LSB) of a byte (unsigned char) * $msb = MSB_byte($value); returns the most significant bit (MSB) of a byte (unsigned char) * $lsb = LSB_short($value); returns the least significant bit (LSB) of an unsigned short * $msb = MSB_short($value); returns the most significant bit (MSB) of an unsigned short * $lsb = LSB_int($value); returns the least significant bit (LSB) of an unsigned int * $msb = MSB_int($value); returns the most significant bit (MSB) of an unsigned int * $lsb = LSB_long($value); returns the least significant bit (LSB) of an unsigned long * $msb = MSB_long($value); returns the most significant bit (MSB) of an unsigned long * $carry = ROL_byte($value); * $carry = ROR_byte($value); * $carry_out = SHL_byte($value,$carry_in); * $carry_out = SHR_byte($value,$carry_in); * $carry = ROL_short($value); * $carry = ROR_short($value); * $carry_out = SHL_short($value,$carry_in); * $carry_out = SHR_short($value,$carry_in); * $carry = ROL_int($value); * $carry = ROR_int($value); * $carry_out = SHL_int($value,$carry_in); * $carry_out = SHR_int($value,$carry_in); * $carry = ROL_long($value); * $carry = ROR_long($value); * $carry_out = SHL_long($value,$carry_in); * $carry_out = SHR_long($value,$carry_in); Requirements: · Perl
