Expand description

Represents floating point arithmetic semantics.

Required Associated Constants

Total number of bits in the in-memory format.

Number of bits in the significand. This includes the integer bit.

The largest E such that 2E is representable; this matches the definition of IEEE 754.

Provided Associated Constants

The smallest E such that 2E is a normalized number; this matches the definition of IEEE 754.

The significand bit that marks NaN as quiet.

The significand bitpattern to mark a NaN as quiet. NOTE: for X87DoubleExtended we need to set two bits instead of 2.
