Output Stack: TimeSeriesExpr

Compute a new time series where each interval has the negated value of the input time series. This applies the unary minus operation, multiplying each value by -1.

Parameters

• expr: The time series expression to negate

Examples

Demonstrating negation with different constant values:

0	64	-64
0,:neg	64,:neg	-64,:neg

This shows that :neg converts 0 to 0, positive values to negative, and negative values to positive.
