# Interface: com.pnfsoftware.jeb.core.units.code.asm.decompiler.ast.ICOperation
- Super interfaces: `com.pnfsoftware.jeb.core.units.code.asm.decompiler.ast.ICLeftExpression`

C AST interface to represent arithmetic and logical expressions.  

  An expression consists of one or two members \(the left and right members\) and an operator. The  left member is optional, and should be null for unary operators.  

  A third member may be specified for [ternary expressions](COperatorType#COND).  

  Examples:    

```

 a + 1
 a * ((int)b - foo())
 !x
 x ^ y | z
 c ? a: b
 
```
