- list of float values: Stores values as list of float.
- text note: Stores note as text.
- floatTrace(text label, text origin, list of float values, text note): Float trace.
- HasValues() returns bool: Has values.
- Count() returns int: Count.
- FirstValue() returns float: First value.
- LastValue() returns float: Last value.
- HasNaN() returns bool: Has na n.
- HasPositiveInfinity() returns bool: Has positive infinity.
- HasNegativeInfinity() returns bool: Has negative infinity.
- HasNonFinite() returns bool: Has non finite.
- NonFiniteCount() returns int: Non finite count.
- Minimum() returns float: Minimum.
- Maximum() returns float: Maximum.
- Span() returns float: Span.
- Describe() returns text: Describe.

## Use floatTrace

A complete small caller. Values are illustrative; check the returned result and package requirements before connecting live resources.

Verification: type checked

```yh
using compute.profiling

// Collect and describe compute timing, work, and profiling records.
floatTrace sample = floatTrace("Player health", "origin", [], "note")
Console.Log(Text.From(sample.label))

```
