abs

Input Stack: expr: TimeSeriesExpr

⇨

Output Stack: TimeSeriesExpr

Compute a new time series where each interval has the absolute value of the input time series. This ensures all values are non-negative by converting negative values to positive while leaving positive values unchanged.

Parameters

• expr: The time series expression to take the absolute value of

Examples

Demonstrating absolute value with different constant values:

0	64	-64
0,:abs	64,:abs	-64,:abs

This shows that :abs converts 0 to 0, leaves positive values unchanged, and converts negative values to positive.

Related Operations

• :neg - Negation (changes sign, compared to abs which removes sign)
• :sub - Subtraction (often used with abs for absolute differences)
• :add - Addition operation
