Round 23.23 to the nearest whole number

Since the .23 is lower than 4 the whole number 23 STAYS THE SAME.

23.0

If the digits after the decimal place are below 50 (1-49) you round down, but if the number is 50-99, you round up. In this case, you would be rounding down, because 23<50. so the answer is 23. I hope my explanation proved helpful and helped you understand :)
