  3. Exponentiation - Wikipedia

    en.wikipedia.org/wiki/Exponentiation

    In mathematics, exponentiation, denoted b n, is an operation involving two numbers: the base, b, and the exponent or power, n. [1] When n is a positive integer, exponentiation corresponds to repeated multiplication of the base: that is, b n is the product of multiplying n bases: [1] = ⏟.

    Or, the number of values representable in a doubleword on a 16-bit processor, such as the original x86 processors. [6] The range of an int variable in the Java, C#, and SQL programming languages. The range of a Cardinal or Integer variable in the Pascal programming language. The minimum range of a long integer variable in the C and C++ ...

    It recommends a number of operations for computing a power: [25] pown (whose exponent is an integer) treats 0 0 as 1; see § Discrete exponents. pow (whose intent is to return a non-NaN result when the exponent is an integer, like pown) treats 0 0 as 1. powr treats 0 0 as NaN (Not-a-Number) due to the indeterminate form; see § Continuous ...

    The floor of x is also called the integral part, integer part, greatest integer, or entier of x, and was historically denoted [x] (among other notations). [2] However, the same term, integer part, is also used for truncation towards zero, which differs from the floor function for negative numbers. For an integer n, ⌊n⌋ = ⌈n⌉ = n.

  7. Modular exponentiation - Wikipedia

    en.wikipedia.org/wiki/Modular_exponentiation

    Modular exponentiation is the remainder when an integer b (the base) is raised to the power e (the exponent), and divided by a positive integer m (the modulus); that is, c = b e mod m. From the definition of division, it follows that 0 ≤ c < m .

    However, do note that a shift operand value which is either a negative number or is greater than or equal to the total number of bits in this value results in undefined behavior. For example, when shifting a 32 bit unsigned integer, a shift amount of 32 or higher would be undefined. Example:

    Yao's method collects in u first those x i that appear to the highest power ⁠ ⁠; in the next round those with power ⁠ ⁠ are collected in u as well etc. The variable y is multiplied ⁠ h − 1 {\displaystyle h-1} ⁠ times with the initial u , ⁠ h − 2 {\displaystyle h-2} ⁠ times with the next highest powers, and so on.
