## Number modulo - int
|
|
If the lhs and rhs are ints then the expression will be calculated with ints.
|
|
|
|
Given a sample.yml file of:
|
|
```yaml
|
|
a: 13
|
|
b: 2
|
|
```
|
|
then
|
|
```bash
|
|
yq '.a = .a % .b' sample.yml
|
|
```
|
|
will output
|
|
```yaml
|
|
a: 1
|
|
b: 2
|
|
```
|
|
|
|
## Number modulo - float
|
|
If the lhs or rhs are floats then the expression will be calculated with floats.
|
|
|
|
Given a sample.yml file of:
|
|
```yaml
|
|
a: 12
|
|
b: 2.5
|
|
```
|
|
then
|
|
```bash
|
|
yq '.a = .a % .b' sample.yml
|
|
```
|
|
will output
|
|
```yaml
|
|
a: !!float 2
|
|
b: 2.5
|
|
```
|
|
|
|
## Number modulo - int by zero
|
|
If the lhs is an int and rhs is a 0 the result is an error.
|
|
|
|
Given a sample.yml file of:
|
|
```yaml
|
|
a: 1
|
|
b: 0
|
|
```
|
|
then
|
|
```bash
|
|
yq '.a = .a % .b' sample.yml
|
|
```
|
|
will output
|
|
```bash
|
|
Error: cannot modulo by 0
|
|
```
|
|
|
|
## Number modulo - float by zero
|
|
If the lhs is a float and rhs is a 0 the result is NaN.
|
|
|
|
Given a sample.yml file of:
|
|
```yaml
|
|
a: 1.1
|
|
b: 0
|
|
```
|
|
then
|
|
```bash
|
|
yq '.a = .a % .b' sample.yml
|
|
```
|
|
will output
|
|
```yaml
|
|
a: !!float NaN
|
|
b: 0
|
|
```
