math

Arc standard library reference for the math module: avg, derivative, max, and min

The math module provides numerical primitives: running averages, running min/max, and derivatives.

avg

Computes a running average of input values, emitting the updated average on each input. By default the average accumulates over every sample; set duration or count to reset the window periodically.

// `flow` only
sensor -> math.avg{} -> output

// Reset by sample count or time window
sensor -> math.avg{count=100} -> output
sensor -> math.avg{duration=5s} -> output

derivative

Computes the rate of change of input values with respect to time. The output is always f64, regardless of the input type.

// `flow` only
sensor -> math.derivative{} -> rate_output

max

Tracks the running maximum of input values, emitting the updated maximum on each input. By default the maximum accumulates over every sample; set duration or count to reset the window periodically.

// `flow` only
sensor -> math.max{} -> output

// Reset by sample count or time window
sensor -> math.max{count=100} -> output
sensor -> math.max{duration=5s} -> output

min

Tracks the running minimum of input values, emitting the updated minimum on each input. By default the minimum accumulates over every sample; set duration or count to reset the window periodically.

// `flow` only
sensor -> math.min{} -> output

// Reset by sample count or time window
sensor -> math.min{count=100} -> output
sensor -> math.min{duration=5s} -> output
