    To put this in perspective, the mass of all such books required to write out a googolplex would be vastly greater than the masses of the Milky Way and the Andromeda galaxies combined (by a factor of roughly 2.0 × 10 50), and greater than the mass of the observable universe by a factor of roughly 7 × 10 39.

  4. Googol - Wikipedia

    en.wikipedia.org/wiki/Googol

    Properties. A googol is approximately 70! ( factorial of 70). [a] Using an integral, binary numeral system, one would need 333 bits to represent a googol, i.e., 1 googol = ≈ 2 332.19280949. However, a googol is well within the maximum bounds of an IEEE 754 double-precision floating point type, but without full precision in the mantissa.

  5. Fixed-point arithmetic - Wikipedia

    Fixed-point arithmetic. In computing, fixed-point is a method of representing fractional (non-integer) numbers by storing a fixed number of digits of their fractional part. Dollar amounts, for example, are often stored with exactly two fractional digits, representing the cents (1/100 of dollar). More generally, the term may refer to ...

    Long division. In arithmetic, long division is a standard division algorithm suitable for dividing multi-digit Hindu-Arabic numerals ( positional notation) that is simple enough to perform by hand. It breaks down a division problem into a series of easier steps. As in all division problems, one number, called the dividend, is divided by another ...
