The isNaN and isInfinity operators check a numeric string and return a boolean value.

  • isNaN returns true if the string value is not a number, false otherwise.
  • isInfinity returns true if the string value is a positive or negative infinity, false otherwise.

Syntax

  • isNaN("<string>") as <field>
  • isNaN(<string_field>) [as <field>]
  • isInfinity("<string>") as <field>
  • isInfinity(<string_field>) [as <field>]

Examples

  • | 5/0 as infinity
    | isInfinity(infinity) as boolean

    Returns boolean as true.
     
  • | parse "has * total tokens" as total_token
    | where !isNaN(total_token)

    Returns results where total_token values are a number.
