Research direction

Start by inspecting the core metrics API and the discussion in the linked sdk-python pull request. Trace where metric values are restricted to integers and compare the industry-standard expectations described there. Done means the Rust core metrics interface accepts both integer and floating-point values with appropriate coverage.

Written by the indexing model from the issue text.

Description

enhancement

Since our goal with metrics is to expose a generic interface for metrics recording in our lang SDKs using industry standards, we should expand the metrics API in core to accept floats and not just ints.
