754r features
For considering today's motions, here's a list of 754r features that the
current standard (754-1985) does not provide:
* decimal floating-point formats and arithmetic
* correct rounding for conversion between internal formats and external
decimal character sequences
* clarification of modes and flags, constant/dynamic alternatives for
mode specification, operations on modes and flags
* fma operations
* arithmetic operations with independent source and destination formats
(formatOf operations)
* round to integer and integral value functions with fixed rounding
direction mode
* conversion with external hexadecimal character sequences
* external character sequences for NaNs and infinities
* compact storage formats
* new rounding mode: to nearest, ties away from zero
* min/max operations
* nextUp, nextDown operations
* upgraded, clarified logB, scaleB specification
* more comparisons, including quiet comparisons
* classification inquiries
* total order operations
* enhanced specification for conversion to integer formats
* clearer, simpler underflow specification
* recommendations for NaN propagation
* recommendations to languages: language-defined behavior, expression
evaluation, wide evaluation, optimization controls
* recommendations for correctly rounded and faithfully rounded
transcendental functions
* recommendation for scaled-product operations
* recommendations for alternate exception handling
* recommendations for debugging support
