1 minus percentage: What is this called?

terminology percentages

I'm trying to convert a percentage:

The original percentage represents how bad the condition of a asset is (in other words, a high number is bad). I would like to convert the percentage to represent how good the condition of an asset is (in other words, a high number is good).

To do this, I can simply subtract the original percentage from 1 to get the desired percentage.

Example:

 1 - 0.25 = 0.75

My question is: What is this called in mathematics? As far as I can tell, this is not the same thing as inverse percentage.


It's called the complement of the percentage. The term comes from probability.
