## DELTA Function

The DELTA function in Google Sheets is used to check whether two numbers are equal. It returns 1 if they are equal, and 0 otherwise.

### Syntax

```
DELTA(number1, [number2])
```

`number1`

: The first number to compare. This is a required parameter.`number2`

: (Optional) The second number to compare. If omitted, it defaults to 0.

### Examples

**Comparing Two Numbers**

Compare the numbers 5 and 5:

```
=DELTA(5, 5)
```

This will output 1, indicating the numbers are equal.

**Comparing Two Different Numbers**

Compare the numbers 5 and 3:

```
=DELTA(5, 3)
```

This will output 0, indicating the numbers are not equal.

**Default Comparison with 0**

Compare the number 2 with 0:

```
=DELTA(2)
```

This will output 0.

### Notes

- The DELTA function is useful in logical operations where numerical equality needs to be tested.
- It can handle both integers and decimal numbers.
