Range functions

A set of functions establish relationships between single scalar values and ranges of such values. All functions take two arguments and return true if the relationship between the argument holds, or false otherwise.

A scalar value must be of the following type:

  • number
  • date
  • time
  • date-time
  • days-time-duration
  • years-months-duration
