Hey @tanishq-singh-2301 did you have any questions or need any help with implementing the latest round of feedback? As a reminder, today is the last today to merge your PRs and have them count toward Hacktoberfest. 👀

HishamT

LGTM!

Dusch4593 · 2022-10-31T21:09:49Z

@tanishq-singh-2301 This looks ready to merge. I just made some changes across many commits prior to merging (cc: @HishamT @SSwiniarski):

Revised the lists in the "Syntax" sections.
- I noticed that the claimed return value for a=0/-0 didn't seem quite right.
Consolidated to a single ```java snippet in the "Example" section.
- Java is not currently supported in Codebytes. 😢
- Adjusted the ```shell output snippets to reflect the revised code.

Hey @tanishq-singh-2301! 👋🏻

I was wondering if you'd be open to creating a new PR to make some edits to the 3 entries you recently contributed?

On line # 2 in each file, can we change the Title to .log(), .log10(), and .log1p() in log.md, log10.md, and log1p.md respectively?

tanishq-singh-2407 · 2022-11-12T03:58:36Z
