  2. TI calculator character sets - Wikipedia

    en.wikipedia.org/wiki/TI_calculator_character_sets

    As part of the design process, Texas Instruments (TI) decided to modify the base Latin-1 character set for use with its calculator interface. By adding symbols to the character set, it was possible to reduce design complexity as much more complex parsing would have to have been used otherwise.

  3. Sign extension - Wikipedia

    en.wikipedia.org/wiki/Sign_extension

    In a move or convert operation, zero extension refers to setting the high bits of the destination to zero, rather than setting them to a copy of the most significant bit of the source. If the source of the operation is an unsigned number, then zero extension is usually the correct way to move it to a larger field while preserving its numeric ...

  4. Exponential-Golomb coding - Wikipedia

    en.wikipedia.org/wiki/Exponential-Golomb_coding

    An exponential-Golomb code (or just Exp-Golomb code) is a type of universal code. To encode any nonnegative integer x using the exp-Golomb code: Write down x+1 in binary; Count the bits written, subtract one, and write that number of starting zero bits preceding the previous bit string. The first few values of the code are:

    List of free analog and digital electronic circuit simulators, available for Windows, macOS, Linux, and comparing against UC Berkeley SPICE.The following table is split into two groups based on whether it has a graphical visual interface or not.

  6. Aiken code - Wikipedia

    en.wikipedia.org/wiki/Aiken_code

    The Aiken code differs from the standard 8421 BCD code in that the Aiken code does not weight the fourth digit as 8 as with the standard BCD code but with 2. Aiken code (symmetry property) Aiken code in hexadecimal coding. The following weighting is obtained for the Aiken code: 2-4-2-1. One might think that double codes are possible for a ...

  7. Reed–Muller code - Wikipedia

    en.wikipedia.org/wiki/Reed–Muller_code

    The Reed–Muller RM(r, m) code of order r and length N = 2 m is the code generated by v 0 and the wedge products of up to r of the v i, 1 ≤ i ≤ m (where by convention a wedge product of fewer than one vector is the identity for the operation).

  8. Calculator input methods - Wikipedia

    en.wikipedia.org/wiki/Calculator_input_methods

    On a single-step or immediate-execution calculator, the user presses a key for each operation, calculating all the intermediate results, before the final value is shown. [1] [2] [3] On an expression or formula calculator, one types in an expression and then presses a key, such as "=" or "Enter", to evaluate the expression.
