(This version truncates results from divide and multiply operations.) There are two attributes of num‐ bers, the length and the scale. The length is the total number of dec‐ imal digits used by bc to represent a number and the scale is the total number of decimal digits after the decimal point.
To figure out what "place" we're at when looking at a decimal-places number, we count up the digits after the decimal point. However many decimal places we have, that's the number of zeroes for the number matching the "place" we're at. For instance, the number 83.295 has three digits after the decimal place (the digits 2, 9, and 5), so the ...
"Decimal" may also refer specifically to the digits after the decimal separator, such as in "3.14 is the approximation of π to two decimals". The numbers that may be represented in the decimal system are the decimal fractions , that is the fractions of the form a /10 n , where a is an integer, and n is a non-negative integer .
Hi. If you need to round the numbers properly, use: =Round(86.656982, 0.01) Using Num() will change the display format, but does not round off the underlying number.
Decimal numbers, such as O.6495, have four digits after the decimal point. Each digit is a different place value. The first digit after the decimal point is called the tenths place value. There are six tenths in the number O.6495. The second digit tells you how many hundredths there are in the number. The number O.6495 has four hundredths.

MATLAB uses IEEE 754 Binary Double Precision to represent floating point numbers. All floating point scheme that use binary mantissas cannot exactly represent 1/10, just like finite decimal representation schemes cannot exactly represent 1/3 or 1/7 .
The collocation decimal places is usually only used in expressions like This value is accurate to four decimal places - meaning the (first) four digits after the decimal point have been specified and are known to be correct. You wouldn't call one of the individual digits a "decimal place".
And that is a Decimal Number!. We can continue with smaller and smaller values, from tenths, to hundredths, and so on, like in this example:. Have a play with decimal numbers yourself: Large and Small. So, our Decimal System lets us write numbers as large or as small as we want, using the decimal point.
To round 231.45 to two significant digits, I'll only use the first three digits; the 2, the 3, and the 1. Because the 1 is followed by a 4, I won't round the 4 up. I'll drop everything after the decimal point. I'll also drop the decimal point itself, since my final sig-dig isn't a zero.
