0.99 to 1 decimal place is 1.0. When rounding to 1 decimal place, you look at the digit in the tenths place (the first digit after the decimal point). If this digit is 5 or greater, you round up; if it is less than 5, you round down. In this case, 0.99 has a 9 in the tenths place, so it rounds up to 1.0.
