# Comparison Operations

> eq, ne, lt, lte, gt, gte, min, max — encrypted comparison and selection

All comparison operations return `ebool`. Equality checks (`eq`, `ne`) work on all encrypted types including `eaddress`. Ordering checks (`lt`, `lte`, `gt`, `gte`) and `min`/`max` work on `euint8 | euint16 | euint32 | euint64 | euint128`.

## Equality

### eq

```solidity theme={null}
ebool isEqual = FHE.eq(a, b);
ebool isEqual = FHE.eq(address1, address2); // eaddress supported
```

### ne

```solidity theme={null}
ebool isNotEqual = FHE.ne(a, b);
```

## Ordering

### lt

```solidity theme={null}
ebool isLess = FHE.lt(a, b);
```

### lte

```solidity theme={null}
ebool isLessOrEqual = FHE.lte(a, b);
```

### gt

```solidity theme={null}
ebool isGreater = FHE.gt(a, b);
```

### gte

```solidity theme={null}
ebool isGreaterOrEqual = FHE.gte(a, b);
```

## Min / Max

### min

```solidity theme={null}
euint32 minimum = FHE.min(a, b);
```

### max

```solidity theme={null}
euint32 maximum = FHE.max(a, b);
```

## Select

Conditionally selects between two encrypted values based on an encrypted boolean. Works on all encrypted types including `eaddress`.

<Tip>
  Use `select` instead of `if/else` statements when working with encrypted values. Conditional branching doesn't work with encrypted data.
</Tip>

```solidity theme={null}
euint8 result = FHE.select(condition, a, b);
eaddress result = FHE.select(condition, addr1, addr2);
```
