stdev

• stdev(a: number, b: number, c: number): number

• Returns the standard deviation of a triangular distribution.

  Notes

  • If the condition a <= c <= b is not satisfied, the function returns NaN.

  Parameters

  • a: number

    minimum support

  • b: number

    maximum support

  • c: number

    mode

  Returns number

  standard deviation

  Example

  var v = stdev( 0.0, 1.0, 0.5 );
  // returns ~0.204

  Example

  var v = stdev( 4.0, 12.0, 9.0 );
  // returns ~1.65

  Example

  var v = stdev( -4.0, 4.0, -1.0 );
  // returns ~1.65

  Example

  var v = stdev( 1.0, -0.1, 0.5 );
  // returns NaN

  Example

  var v = stdev( 0.0, 1.0, 2.0 );
  // returns NaN

  Example

  var v = stdev( NaN, 4.0, 2.0 );
  // returns NaN

  Example

  var v = stdev( 0.0, NaN, 2.0 );
  // returns NaN

  Example

  var v = stdev( 0.0, 4.0, NaN );
  // returns NaN
