The G symbol used after an angle makes sure the angle is interpreted as being in gradians (an obscure angle measure in which a full circle is equal to 400 gradians); this functionality is present only on TI-89 Titanium or Voyage 200 calculators with AMS version 3.10. If the calculator is already in gradian mode, xG is equal to x; in degree mode, xG is equal to 9*x/10; and in radian mode, xG is equal to π*x/200.

If you're using gradian angle measures extensively in a program, it's a better idea to use setMode() to switch to gradian mode and not worry about this. However, there are two reasons you might want to use G:

  • If you need an angle in gradians only once or twice, don't bother changing the mode setting.
  • In a function, you're forced to use G, since setMode() isn't valid in a function.

In gradian mode (no conversion is necessary, so no conversion is done):


In degree mode:
