`<cumulativeMax>`

Running maximum of the child math or number valuesAdded in 0.7.27

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

Where <max> reduces a list to a single value, <cumulativeMax> produces a list the same length as its input. The result never decreases.

Examples

Example: running maximum

Each entry is the largest value seen so far, so the list is non-decreasing and its last entry is the <max> of the whole input.

Example: a personal best

Pairing <cumulativeMax> with the original list shows when a record was set: the running maximum changes exactly on those attempts.
