  2. Parity of zero - Wikipedia

    en.wikipedia.org/wiki/Parity_of_zero

    That is, the numbers read 6-4-2-0-1-3-5 from port to starboard. [70] In the game of roulette, the number 0 does not count as even or odd, giving the casino an advantage on such bets. [71] Similarly, the parity of zero can affect payoffs in prop bets when the outcome depends on whether some randomized number is odd or even, and it turns out to ...

  3. Parity (mathematics) - Wikipedia

    en.wikipedia.org/wiki/Parity_(mathematics)

    That is, if the last digit is 1, 3, 5, 7, or 9, then it is odd; otherwise it is even—as the last digit of any even number is 0, 2, 4, 6, or 8. The same idea will work using any even base. In particular, a number expressed in the binary numeral system is odd if its last digit is 1; and it is even if its last digit is 0. In an odd base, the ...

    en.wikipedia.org/wiki/Conditional_operator

    condition: An expression which is evaluated as a boolean value. expression 1, expression 2: Expressions with values of any type. If the condition is evaluated to true, the expression 1 will be evaluated. If the condition is evaluated to false, the expression 2 will be evaluated.

  5. Relational operator - Wikipedia

    en.wikipedia.org/wiki/Relational_operator

    In languages such as C, relational operators return the integers 0 or 1, where 0 stands for false and any non-zero value stands for true. An expression created using a relational operator forms what is termed a relational expression or a condition. Relational operators can be seen as special cases of logical predicates.

  6. Even and odd functions - Wikipedia

    en.wikipedia.org/wiki/Even_and_odd_functions

    A real function f is even if, for every x in its domain, −x is also in its domain and [1]: p. 11 = or equivalently () = Geometrically, the graph of an even function is symmetric with respect to the y -axis, meaning that its graph remains unchanged after reflection about the y -axis.

  7. Conditional (computer programming) - Wikipedia

    en.wikipedia.org/wiki/Conditional_(computer...

    The above example takes the conditional of Math.random() < 0.5 which outputs true if a random float value between 0 and 1 is greater than 0.5. The statement uses it to randomly choose between outputting You got Heads! or You got Tails! to the console. Else and else-if statements can also be chained after the curly bracket of the statement ...

  8. Divisibility rule - Wikipedia

    en.wikipedia.org/wiki/Divisibility_rule

    Divisibility condition Examples 1: No specific condition. Any integer is divisible by 1. 2 is divisible by 1. 2: The last digit is even (0, 2, 4, 6, or 8). [2] [3]

  9. Sign function - Wikipedia

    en.wikipedia.org/wiki/Sign_function

    Signum function = ⁡. In mathematics, the sign function or signum function (from signum, Latin for "sign") is a function that has the value −1, +1 or 0 according to whether the sign of a given real number is positive or negative, or the given number is itself zero.
