unicorn/no-zero-fractions

1.0, 1. and 1 are the same number. JavaScript has no separate integer and float types, so the extra zeros and the dot suggest a difference that isn't there.

--fix removes the zeros and the dot.

Configure

Off by default. To turn it on:

[lint.rules]
"unicorn/no-zero-fractions" = "error" # or "warn"
