Description is highly lacking:

• input range is not stated
• amount of decimal values the input can have (i.e. is it only limited to numbers such as 0.6, 0.7, 0.8 or can numbers such as 0.65 that have more than a tenths digit also appear?)

Needs random tests,

Or at least more comprehensive tests. I mistakenly used roundinstead of int in my solution, and it shouldn't have passed, but it did.
