Does Logarithm upload my file or text to Tool-You servers?

No. Logarithm runs in this browser tab. Files stay on the device. Limit note: Value>0, base>0, base≠1.

Should I use Power X^Y instead of Logarithm?

Use Logarithm when you need Log with ln and base. Use Power X^Y when you need Power with base/exp. They share a category (Calculate) but not the same job.

Logarithm

Log with ln and base.

Logarithm log_b(v) for any positive base and value. Also shows ln(v) so you can compare natural log with the custom base in one view.

What Logarithm does

Logarithm log_b(v) for any positive base and value. Also shows ln(v) so you can compare natural log with the custom base in one view.

Logarithm sits in the Calculate group on purpose. It is not Power X^Y (Power with base/exp.) and not Nth Root (Nth root with degree.). Choose this page when you need Log with ln and base. If you stretch Logarithm into a neighbor’s job, the result will look wrong even though the site chrome looks the same.

How to use Logarithm

Confirm you need Logarithm, not Power X^Y (Power with base/exp.). Address: /log-base.
Enter the numbers or dates Logarithm uses. Log with ln and base.
Read the result as Logarithm defines it — not as Nth Root (Nth root with degree.). Logarithm log_b(v) for any positive base and value. Also shows ln(v) so you can compare natural log with the custom base in one view.
Logarithm is an estimate in the browser, not professional advice. Value>0, base>0, base≠1.
Need a different formula? Try Nth Root (Nth root with degree.) instead of stretching Logarithm.

When not to use Logarithm

Skip Logarithm when a neighbor tool matches better — start with Power X^Y or Nth Root — or when the description already warns the job will fail. In the tool’s own words: Logarithm log_b(v) for any positive base and value. Also shows ln(v) so you can compare natural log with the custom base in one view.
