The precision is determined by the POSITION of the number 6 - NOT its value.
The number must start with 3.2 and the next digit can be anything from 0 to 5. With two exceptions, these can be followed by any sequence of digits. Exception 1: Where the third digit is 0, it must have some non-zero number following because otherwise, it will be 3.200... which is 3.2 Exception 2: Where the third digit is 5, it must have some digit which is not 9 following because otherwise, it will be 3.25999... which is 3.26
9999 is the 4-digit number and 999 is the 3-digit number.
the leading digit
A digit is a number or numeral. A dividend is a number to be divided. A dividend is divided by a divisor to yield a quotient. A digit dividend is a single digit number that is being divided some other (non-specified) number. The word single is assumed to be there. It could be written like this: A (single) digit dividend is a single digit number that is being divided by another number. In mathematics, there are 1-digit dividends, 2-digit dividends, etc.
It has no precision, since there is no following number.
The "2".
The last digit, 2.
In this case with 234.896 the last digit, '6' determines the precision since in is the last non-zero digit.

The farthest to the right.
Always the last number, so in this example the precision is to hundredths.
If a number is given to the true degree of precision, this is always determined by its last digit - in this case, 6.
None of them, you do that! You have given it to the precision of 3 decimal places or 6 significant figures however.
