speculable  exu stream  exu block  compute phase   operation   in the binary floating point value domain  

native on: Silver

Produce an enum value to classify binary floating points into normal values, subnormals, infinities and NaNs etc.

The exact list is:

  • signaling NaN,
  • quiet NaN,
  • negative Infinity,
  • negative Normal,
  • negative Subnormal,
  • negative Zero,
  • positive Zero,
  • positive Subnormal,
  • positive Normal,
  • positive Infinity

classifyf(f x) → f r0

operands: like Addf [ff:f]
