Arity

Unary — abs <number>.

abs <number>

Description

Returns the absolute (non-negative) value of a number. abs -5 → 5, abs 3 → 3. Auto-unwraps shared values.

How It Works

Calls Math.Abs(double). Negative input becomes positive; positive input unchanged; zero unchanged.

Usage

abs -5;                        // 5
abs 3.14;                      // 3.14
abs 0;                         // 0

// Distance / magnitude
_delta = abs (_a - _b);

// Error margin
if (abs (_actual - _expected) < 0.001) then {
    systemChat "Values match";
};
