Expand description

Condition code for comparing floating point numbers.

This condition code is used by the fcmp instruction to compare floating point values. Two IEEE floating point values relate in exactly one of four ways:

  1. UN - unordered when either value is NaN.
  2. EQ - equal numerical value.
  3. LT - x is less than y.
  4. GT - x is greater than y.

Note that 0.0 and -0.0 relate as EQ because they both represent the number 0.

The condition codes described here are used to produce a single boolean value from the comparison. The 14 condition codes here cover every possible combination of the relation above except the impossible !UN & !EQ & !LT & !GT and the always true UN | EQ | LT | GT.
