k - My grades include decimals, but I can only enter whole numbers. What should I do?

You should round off all figures to a whole number in the following way:

• 0,000 – 0,499 ⇒ 0
• 0,500 – 1,499 ⇒ 1
• 1,500 – 2,499 ⇒ 2
• 2,500 – 3,499 ⇒ 3
• 3,500 – 4,499 ⇒ 4
• 4,500 – 5,499 ⇒ 5
• 5,500 – 6,499 ⇒ 6
• 6,500 – 7,499 ⇒ 7
• 7,500 – 8,499 ⇒ 8
• 8,500 – 9,499 ⇒ 9
• 9,500 – 9,999 ⇒ 10
