Hello,

I am attempting to use etoolbox for various logical operators to conditionally write text. I ultimately want to use \ifboolexpr, but I can't seem to understand how \ifstrequal behaves. Specifically, I am getting two outputs when a condition is met. Is this intended? Am I using this incorrectly? I am not sure how I could provide the output of my working example, but I get:

Test1: TRUETRUE
Test2: FALSEFALSE

Thank you in advance for taking the time to read and reply.

-Alan

Working Example:

---
output: pdf_document
header-includes:
  - \usepackage{etoolbox}
---

Test1: \ifstrequal{hello}{hello}{TRUE}{FALSE}

Test2: \ifstrequal{hello}{world}{TRUE}{FALSE}
