# Divide

Divide behaves differently according to the type of the LHS:
* strings: split by the divider
* number: arithmetic division

## String split
Given a sample.yml file of:
```yaml
{a: cat_meow, b: _}
```
then
```bash
yq '.c = .a / .b' sample.yml
```
will output
```yaml
{a: cat_meow, b: _, c: [cat, meow]}
```

## Number division
The result during division is calculated as a float

Given a sample.yml file of:
```yaml
{a: 12, b: 2.5}
```
then
```bash
yq '.a = .a / .b' sample.yml
```
will output
```yaml
{a: 4.8, b: 2.5}
```

## Number division by zero
Dividing by zero results in +Inf or -Inf

Given a sample.yml file of:
```yaml
{a: 1, b: -1}
```
then
```bash
yq '.a = .a / 0 | .b = .b / 0' sample.yml
```
will output
```yaml
{a: !!float +Inf, b: !!float -Inf}
```
