Won't start after installation due to float and string comparisons

[tjohnman]

Describe the bug

Yin-Yang does not start.

Affected versions

• Yin-Yang version:
  I tried building master and beta from source. I also tried the 3.2.4 release package.

Additional notes

These are the errors that the script encounters on launch:
