Export assignment roundb

• roundb(x: number, n: number, b: number): number

• Rounds a numeric value to the nearest multiple of \(b^n\) on a linear scale.

  Notes

  • Due to floating-point rounding error, rounding may not be exact.

  Parameters

  • x: number

    input value

  • n: number

    integer power

  • b: number

    positive integer base

  Returns number

  rounded value

  Example

  // Round a value to 2 decimal places:
  var v = roundb( 3.141592653589793, -2, 10 );
  // returns 3.14

  Example

  // If n = 0 or b = 1, `roundb` behaves like `round`:
  var v = roundb( 3.141592653589793, 0, 2 );
  // returns 3.0

  Example

  // Round a value to the nearest multiple of two:
  var v = roundb( 5.0, 1, 2 );
  // returns 6.0
