mean

• mean(a: number, b: number): number

• Returns the expected value of a discrete uniform distribution.

  Notes

  • If a or b is not an integer value, the function returns NaN.
  • If provided a >= b, the function returns NaN.

  Parameters

  • a: number

    minimum support

  • b: number

    maximum support

  Returns number

  expected value

  Example

  var v = mean( 0, 1 );
  // returns 0.5

  Example

  var v = mean( -4, 4 );
  // returns 0.0

  Example

  var v = mean( 0, 10 );
  // returns 5.0

  Example

  var v = mean( 1, -0.1 );
  // returns NaN

  Example

  var v = mean( -0.1, 1 );
  // returns NaN

  Example

  var v = mean( 2, NaN );
  // returns NaN

  Example

  var v = mean( NaN, 2 );
  // returns NaN
