FBNDXX

Operation

Checks floating-point value membership in the exclusive-exclusive interval (lo, hi).

Assembler Syntax

FBNDXX.{S|D}(z) Fn(l), Fn(v), Fn(h)

FBNDXX.{S|D}(z) Fn(l), <ea>(v), Fn(h)

FBNDXX.{S|D}(z) <ea>(l), Fn(v), <ea>(h)

Privilege

Required CPUID flags

FBNDXX treats both bounds as exclusive. It sets FLAGS.V when the value is unordered or outside (lo, hi) and clears FLAGS.Z, FLAGS.N, and FLAGS.C. IEEE-754 FFLAGS causes continue to accrue independently.
