Definition

number abs(number $value)

If $value is a number, returns the absolute value of the argument, equal to $value if $value is greater or equal to zero, and -$value if $value is less or equal to zero.

Parameters

number $value

Number to calculate the absolute value of.

Returns

A number greater or equal to zero, the absolute value of $value.

Examples

{
  negativeNum: abs(`-1`),
  positiveNum: abs(`2`),
  stringNum: abs('3.0'),
  truth: abs(`true`),
  falsity: abs(`false`),
  none: abs(`null`),
  text: abs(`"text"`),     // Error
  array: abs(`[]`),        // Error
  object: abs(`{}`)        // Error
}

{
  "negativeNum": 1,
  "positiveNum": 2,
  "stringNum": 3.0,
  "truth": 1.0,
  "falsity": 0.0,
  "none": 0.0
}

Remarks

Accepts Boolean, null and strings with correct number format arguments as well, in which case the argument is converted to number implicitly before calculating the absolute value. Other argument types raise an Error and return null.
