FXDVCK - set quotient to return for a divide check.


call fxdvck(float [, int])


is the double-precision value that is to be used after a floating point divide check.
is the integer that is to be used after an integer divide check.


FXDVCK allows the program to specify what value should be returned as the quotient from any subsequent divide check faults. If FXDVCK is not called, a floating divide check will return the largest floating point value, and an integer divide check will return the dividend.

If a divide check fault occurs while using the intrinsic function MOD, the result is undefined even if FXDVCK has been used.
