  2. Numeric precision in Microsoft Excel - Wikipedia

    en.wikipedia.org/wiki/Numeric_precision_in...

    Excel's storage of numbers in binary format also affects its accuracy. [3] To illustrate, the lower figure tabulates the simple addition 1 + x − 1 for several values of x. All the values of x begin at the 15 th decimal, so Excel must take them into account. Before calculating the sum 1 + x, Excel first approximates x as a binary number

  3. Leading zero - Wikipedia

    en.wikipedia.org/wiki/Leading_zero

    A leading zero is any 0 digit that comes before the first nonzero digit in a number string in positional notation. [1] For example, James Bond 's famous identifier, 007, has two leading zeros. [ 2 ] Any zeroes appearing to the left of the first non-zero digit (of any integer or decimal) do not affect its value, and can be omitted (or replaced ...

  4. Trailing zero - Wikipedia

    en.wikipedia.org/wiki/Trailing_zero

    However, trailing zeros may be useful for indicating the number of significant figures, for example in a measurement. In such a context, "simplifying" a number by removing trailing zeros would be incorrect. The number of trailing zeros in a non-zero base-b integer n equals the exponent of the highest power of b that divides n.

  5. Significant figures - Wikipedia

    en.wikipedia.org/wiki/Significant_figures

    If it is the rough estimation, then only the first three non-zero digits are significant since the trailing zeros are neither reliable nor necessary; 45600 m can be expressed as 45.6 km or as 4.56 × 10 4 m in scientific notation, and neither expression requires the trailing zeros. An exact number has an infinite number of significant figures.

  6. Find first set - Wikipedia

    en.wikipedia.org/wiki/Find_first_set

    This is closely related to count leading zeros (clz) or number of leading zeros (nlz), which counts the number of zero bits preceding the most significant one bit. [ nb 2 ] There are two common variants of find first set, the POSIX definition which starts indexing of bits at 1, [ 2 ] herein labelled ffs, and the variant which starts indexing of ...

    All numbers in Thailand, whether for landlines or mobile reception, consist of eight digits, xxxx xxxx in the government's official format. When calling domestically, landline numbers are preceded by a zero (0 xxxx xxxx, example 0 5381 0595) while mobile numbers are preceded by 0 plus one digit (0x xxxx xxxx, example 06 9756 4509).
