Re: Motion 24.03: NO



Dear 1788 members,

The motion says:
"   Every IEEE 1788 compliant system shall provide the four basic arithmetic
operations addition, subtraction, multiplication, and division with rounding downwards and
upwards. Type conversions with directed roundings shall also be provided."

If we decide to base 1788 on 754 then I do not see any need for this specific motion. Any 754 compliant system MUST provide what this motion requires. The relevant part from 754-2008 is on page 16:

"An implementation of this standard shall provide roundTiesToEven and the three directed rounding
attributes. A decimal format implementation of this standard shall provide roundTiesToAway as a user-
selectable rounding-direction attribute. The rounding attribute roundTiesToAway is not required for a
binary format implementation."

In order to correctly keep what is 754 within 754 and what is 1788 within 1788 I vote NO on motion 24.03.
