This is further modulated by the number of bit positions a given value shall be shifted, such as " shift left by 1 " or " shift right by n ".
22.
For an example the PDP-10 byte pointer contained the size of the byte in bits ( allowing different-sized bytes to be accessed ), the bit position of the byte within the word, and the word address of the data.
23.
The IBM 7070, IBM 7072, and IBM 7074 computers used this code to represent each of the ten decimal digits in a machine word, although they numbered the bit positions 0-1-2-3-4, rather than with weights.
24.
Wilkinson chose the perturbation of 2 & minus; 23 because his Pilot ACE computer had 30-bit floating point significands, so for numbers around 210, 2 & minus; 23 was an error in the first bit position not represented in the computer.
25.
For example, given the primitive polynomial, we start with a user-specified 10-bit seed occupying bit positions 1 through 10, starting from the least significant bit . ( The seed need not randomly be chosen, but it can be ).
26.
By arranging the fields so that the sign bit is in the most significant bit position, the biased exponent in the middle, then the mantissa in the least significant bits, the resulting value will be ordered properly, whether it's interpreted as a floating point or integer value.
27.
The number of valid characters in CCIR 476 is the number of ways to choose 4 marks for 7 bit positions, and the number can be calculated using the binomial coefficient : \ textstyle \ binom { 7 } { 3 } = \ binom { 7 } { 4 } = 35.
28.
Alternative schemes were also available where " H " and " L " or " 0 " and " 1 " were also available to represent data bits, but in both of these encoding schemes, the two data-bearing ASCII characters differ in only one bit position, providing very poor single punch error detection.
29.
For example, if given the truth table for the arithmetic sum bit " u " of one bit position's logic of an adder circuit, as a function of " x " and " y " from the addends and the carry in, " ci ":

In the construction of Gray codes, sequences of binary values with the property that consecutive sequence values differ from each other in a single bit position, a number can be converted into the Gray code value at position of the sequence simply by taking the exclusive or of and ( the number formed by shifting right by a single bit position ).
