  2. cos(‘Number Field’)


  • cos is the function keyword. This must be entered into the Ninox function editor in all lower-case characters
  • numeric value is a specified numeric value
  • ‘Number Field’ is the reference name of a Number Field in a table, the contents of which are to serve as the basis for the cos calculation.


  • cos(-1) = -0.540302305868
  • cos(0) = 1
  • cos(1) = 0.540302305868
