⚠️ Tracking Issue Closure Warning ⚠️

I noticed your PR description contains closing keywords ("Resolves", "Closes", or "Fixes") referencing a "Tracking Issue".

Why this matters:
Tracking issues should typically remain open until all related sub-issues are completed. GitHub automatically closes issues with such closing keywords when the PR is merged. For more information, see GitHub's documentation on using keywords in issues and pull requests.

Required action:
Use "Progresses" instead to reference the tracking issue without automatically closing it.

Thank you for your contribution to the project!

+#include "stdlib/math/base/special/exp.h"


@nirmaljb We will require the single-precision implementation of exp here (which we currently don't have) , right?

Yes! You can block this PR for the time being.

The pr needs to blocked untill expf gets merged.

Missing @private tag. See cexp/lib/native.js.

+bench( format( '%s', pkg ), function benchmark( b ) {


pkg is already a string; wrapping it in format( '%s', pkg ) is a no-op. Pass it directly and drop the format import on line 25.

Suggested change

bench( format( '%s', pkg ), function benchmark( b ) {

bench( pkg, function benchmark( b ) {
