    A six-bit word containing the binary encoded representation of decimal value 40. Most modern CPUs employ word sizes that are a power of two, for example 8, 16, 32 or 64 bits. Related to numeric representation is the size and precision of integer numbers that a CPU can represent.

  6. Pell's equation - Wikipedia

    Products of such matrices take exactly the same form, and thus all such products yield solutions to Pell's equation. This can be understood in part to arise from the fact that successive convergents of a continued fraction share the same property: If p k−1 /q k−1 and p k /q k are two successive convergents of a continued fraction, then the ...
