Returns the absolute value of a number.
$absolute(number)
where
number | a number, or an expression that evaluates to a number |
Number, positive, with the same number of decimal places as number.
Use $absolute to ensure that a number is positive (for functions such as $sqrt, for example). $absolute returns the absolute (unsigned) value of a number. The absolute value is always treated as positive.
Certain functions - for example, $sqrt - accept only positive arguments. You can use $absolute to ensure that all arguments to these functions are positive.
$sqrt($absolute(-0.98))
evaluates as if it were:
$sqrt(0.98)
