abs static method

Value abs(Object argument)

Creates an abs() calculation with the given argument.

The argument must be either a SassNumber, a SassCalculation, an unquoted SassString, or a CalculationOperation.

This automatically simplifies the calculation, so it may return a SassNumber rather than a SassCalculation. It throws an exception if it can determine that the calculation will definitely produce invalid CSS.

Implementation

static Value abs(Object argument) {
  argument = _simplify(argument);
  if (argument is! SassNumber) return SassCalculation._("abs", [argument]);
  if (argument.hasUnit("%")) {
    warnForDeprecation(
        "Passing percentage units to the global abs() function is deprecated.\n"
        "In the future, this will emit a CSS abs() function to be resolved by the browser.\n"
        "To preserve current behavior: math.abs($argument)"
        "\n"
        "To emit a CSS abs() now: abs(#{$argument})\n"
        "More info: https://sass-lang.com/d/abs-percent",
        Deprecation.absPercent);
  }
  return number_lib.abs(argument);
}
