The ►Rect command can be used when displaying a complex number on the home screen, or with the Disp and Pause commands. It will then format the number as though a+bi mode were enabled, even when it's not. It also works with lists.


It will also work when displaying a number by putting it on the last line of a program by itself. It does not work with Output(, Text(, or any other more complicated display commands.

To actually separate a number into the components of rectangular form, use real( and imag(.

Error Conditions

  • ERR:SYNTAX is thrown if the command is used somewhere other than the allowed display commands.
  • ERR:DATA TYPE is thrown if the value is real.
