ALTFP_CONVERT truth table missing

Hi, 

I'm using the ALTFP_CONVERT megafunction to convert between FP44 and FP32 domains back-and-forth. The megafunction offers optional NaN, overflow and underflow flag outputs - however, the Floating-Point Megafunction User Guide (version UG-01063-3.0, July 2010) does not give a truth table for the converter operation, as e.g. for the multiplier or adder. 

 

So, here my question: does the converter function include exception handling, rendering the flag outputs just 'informal', or will I need to add my own exception handling for the converter output based on the flags? 

 

Every hint appreciated!
