Enum cranelift_codegen_shared::condcodes::FloatCC [−][src]
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:
UN
- unordered when either value is NaN.EQ
- equal numerical value.LT
-x
is less thany
.GT
-x
is greater thany
.
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
.
Variants
EQ | LT | GT

The C ‘!=’ operator is the inverse of ‘==’: NotEqual
.
