In short: Yes 193.49 is correct.
The first digit place after the decimal is the tenths place. The second digit place after the decimal is the hundredths.
Thus, you should be looking at the next place over. If the number is less than five, then you are going to round down i.e. simply truncate to two decimal places.
The other case: If the thousandths digit is greater or equal to 5, you are going to round up i.e. Increase the hundredth's digit by one and truncate to two decimal places.
