Custom power multiplier doesn't show correct number

When adding new recipes and setting power multiplier to numbers like 125% or 250% - the UI doesn't show it properly (as can be seen on screenshots).

The first screenshot should show 1.25x instead of 1x, and second 2.5x instead 3x.

I'm guessing that the game forcibly rounds normaly,
to no digits after the decimal point 🤔.

Only if value is greater than 1. If below 1, it shows.
