## Working with string, number and boolean values
|
|
### Set and get boolean value and provide default value in case it is not set
|
|

|
|
|
### Set and get string value
|
|
<snippet id='application-settings-string'/>
|
|
|
|
### Set and get numeric value.
|
|
We use `toFixed()` here in order to avoid floating point errors - ex: `54.321` becoming `54.320999999537`.
|
|
Beware the result of `toFixed()` is a string not a number therefore you cannot use `===` or `!==` when comparing with a number.
