# Mathematical functions

## intDiv

Usage:

```
intDiv(a, b)
```

Divide `a` by `b`, rounding the answer down to the nearest whole number.

## log New

Usage:

```
log(<expression>)
```

`log` returns the natural logarithm of a provided number. `ln` is also available as an alias.

Examples:

```
-- get the natural logarithm of the double1 columnlog(double1)
```

## pow New

Usage:

```
pow(<expression>, <expression>)
```

`pow` returns the first argument raised to the power of the second argument.

Examples:

```
-- get the square of the double1 columnpow(double1, 2)
```

## round New

Usage:

```
round(<expression>[, n])
```

`round` returns a number rounded to the nearest whole number, or to a given number of decimal points specified by the second argument.

Examples:

```
-- round 5.5 to 6round(5.5)-- round 3.14 to 3.1round(3.14, 1)
```

## floor New

Usage:

```
floor(<expression>[, n])
```

`floor` returns a number rounded down to a whole number, or rounded down to a given number of decimal points specified by the second argument.

Examples:

```
-- round down 5.5 to 5floor(5.5)-- round down 3.14 to 3.1floor(3.14, 1)
```

## ceil New

Usage:

```
ceil(<expression>[, n])
```

`ceil` returns a number rounded up to a whole number, or rounded up to a given number of decimal points specified by the second argument.

Examples:

```
-- round up 5.5 to 6ceil(5.5)-- round up 3.14 to 3.2ceil(3.14, 1)
```
