These are quick intro slides for ARITH-17's panel on "Arithmetic Interactions".

Modern Language Tools and 754R E. Jason Riedy UC Berkeley

Current State: HW Designers SW Designers ● Can implement ● Few implementation anything! options. No feedback on No access to Languages ● ● trade-offs. features. ● Not bridging the gap. ● What can 754R do?

● Current 754 support is ad-hoc. ● C99, Fortran 2003 provide different descriptions for same model. ● Many languages provide no semantics. ● Compilers provide less... ● 754R: Provide a language for languages. ● Not LIA: Describe 754 arithmetic, not all possible arithmetics. ● Use modern language tools: Type theory and inferencing.

Typing from 20k Feet ● Precisions ≈ data types ● Operations ≈ function types ● Expression evaluation rules ⊂typing rules

Impact on 754R ● Provides a sound base for definitions. ● Could define typing hierarchy and “literal” type for wide expression evaluation. – Assists interval arithmetic! ● Models modes and flags: – ● Possible problems: – Comparison operators and wide eval? – Compiler support?
