dio_is_display_dec(_c)

	status.i4.v = dio_is_display_dec(device_index.i4.r, property.i2.r)

	status.i4.v = dio_is_display_dec_c(device_index.i4.v, property.i2.v)

	This function returns the default display format for a device and
	property (DI/PI).
	
	device_index	device index
	property	property index
			(PRREAD -> reading property,
			 PRSET -> setting property)

	This function returns status values as follows:

	DIO_BADARG		invalid property index passed
	TRUE			standard decimal notation
	FALSE			scientific notation

	This function requires the following include files:

	cnsparam_h, dbprops_h, diolib_h, acnet_errors_h
