Returns the modified Bessel function In(x).

Sample Usage

BESSELI(2.5,1)
BESSELI(C5,C6)

Syntax

BESSELI(x,n)

  • x - The value on which the function will be calculated.
  • n - The order of the Bessel function.

Examples

BESSELI(2.5,1) returns the modified Bessel function at 2.5 with an order of 1.
BESSELI(C5,C6) returns the modified Bessel function, according to the arguments specified in cells C5 and C6.

Notes

  • If n is not an integer, it is truncated.
  • If n < 0, BESSELI returns an error. 
  • If n is nonnumeric, BESSELI returns an error.
