The answer depends on the data source. Exchange rates are usually accurate to 6 significant digits.
If two decimal numbers have x and y digits after the decimal point respectively, then their product has (x + y) digits after the decimal point.
Yes, it can.
It is a terminating decimal.
I think it's a repeating decimal.
It is a decimal fraction.
Digits after (to the right of) the decimal point contribute to the accuracy of the number, not its magnitude (or size). So only the digits to the left of the decimal point contribute to the magnitude. Digits after (to the right of) the decimal point contribute to the accuracy of the number, not its magnitude (or size). So only the digits to the left of the decimal point contribute to the magnitude. Digits after (to the right of) the decimal point contribute to the accuracy of the number, not its magnitude (or size). So only the digits to the left of the decimal point contribute to the magnitude. Digits after (to the right of) the decimal point contribute to the accuracy of the number, not its magnitude (or size). So only the digits to the left of the decimal point contribute to the magnitude.
You must add 9 digits (or 12 digits, depending on the country) after the decimal point, and eliminate the decimal point. Thus (assuming the "short scale") you get: 53,620,000,000.You must add 9 digits (or 12 digits, depending on the country) after the decimal point, and eliminate the decimal point.

One way is to multiply the numbers ignoring the decimal point. If the first multiplicand has d1 digits after the decimal point, and the second has d2 digits after the decimal point, then their product has (d1 + d2) digits after the decimal point.An alternative for the second stage is to estimate the answer to determine where the decimal point should go.
If two decimal numbers have x and y digits after the decimal point respectively, then their product has (x + y) digits after the decimal point.
If the two decimal numbers have x and y digits after the decimal points, then the product has (x + y) digits after the decimal point.
When using front-end estimation, we add or subtract the front digits, and then adjust for a more accurate estimation by estimating the sum of the digits to the right of the decimal point.
If it ever ends, then it is.If there are no digits after the decimal point, it's an integer.
Yes, it can.
Only if the final digit, after the decimal point, is zero.
You need to add up the number of digits to the right of the decimal to find the number of digits in the answer. If the first factor has 2 digits to the right of the decimal point and the second factor has 3, the final answer will have 5 digits to the right of the decimal point.
the answer is it stays in the same place.* * * * *Not quite.Suppose you want to multiply two decimal numbers A and B. Multiply the two numbers ignoring the decimal points.Count the number of digits after the decimal point in the number A.Count the number of digits after the decimal point in the number B.Add these two numbers together. This is the number of digits you want after the decimal point in the answer. So count back from the end.Example:2.54 * 3.5 (this is number of centimetres in 3.5 inches)254*35 = 8890Number of digits after the decimal point in 2.54 is 2 (5 and 4).Number of digits after the decimal point in 3.5 is 1 (5).2 + 1 = 3 so there must be 3 digits after the decimal point in the answer.Therefore 8890 becomes 8.890NOW, you can simplify it to 8.89
