The shape of it

Syntax

Worked examples

  • One

    The square root of pi.

  • Two

    =SQRTPI(2) 2.506628275

    Square root of 2 pi, the normal density constant.

  • Four

    =SQRTPI(4) 3.544907702

    Twice the square root of pi.

Worth knowing

  • The normal density is EXP(-z^2/2)/SQRTPI(2).
  • Same as SQRT(x*PI()).
  • Input must be non-negative.

Where it goes wrong

  • #NUM! for negative input.
  • Rarely needed; NORM.DIST already includes the constant.
