Float numbers and strange percentages

Hi!

Which numbers look easier and more informative, 12.3 or 12, 14.7 or 15? The answer is obvious. Float numbers can be used for internal calculations, but it is advisable to display them rounded. But the 24% and 48% confuse me the most. Where are the missing percentages lost? In mathematics, there is a concept of a whole (100%), three quarters (75%), a half (50%) and a quarter (25%). It seems to me that the phrase 'weapon reload time decreased by a quarter' sounds much better than the similar phrase with 24 percent. For values ​​given as percentages, it is much better to use numbers that are multiples of five and ten.
