It depends on what you are starting with. If you have the current expressed in phasor notation with respect to voltage, it is the tangent of the phase angle.

which means that if the current and voltage are 90 degrees out of phase then the power factor is infinite, is that correct?

Theoretically, since for purely reactive power, no work would actually get done. I doubt this ever occurs in practice, so it is not a concern. (I will leave a detailed discussion of this to those whose power engineering knowledge are more robust than mine.)

that seems like a good idea, especially since Wikipedia says that the power factor PF has the property -1 <= PF <= 1 ( 0<= PF <= 1 if the device is a load as opposed to a source ).
