{%snippet application-settings-require%}

## Working with string, number and boolean values
### Set and get boolean value and provide default value in case it is not set
{%snippet application-settings-boolean%}

### Set and get string value
{%snippet application-settings-string%}

### Set and get numeric value.
Use this method to set numbers with floating point and up to 9 digits long. For larger numbers use `setString`.
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.
