# FXDVCK - set quotient to return for a divide check.

### Usage:

call fxdvck(float [, int])

### Where:

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

### Description:

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.
