`<cumulativeMin>`

Running minimum of the child math or number valuesAdded in 0.7.27

<cumulativeMin> is a Math Operator component that renders the running minimum of its arguments: a list whose $n$ th entry is the smallest of the first $n$ input values.

Where <min> reduces a list to a single value, <cumulativeMin> produces a list the same length as its input. The result never increases.

Examples

Example: running minimum

Each entry is the smallest value seen so far, so the list is non-increasing and its last entry is the <min> of the whole input.

Example: a record low

A running extreme answers “what is the best (or worst) result so far?” at every point in a list, which a single <min> cannot express.
