The last digit, 6, determines its precision. 234.896 is presumed to be accurate to the nearest thousandth. If any other digit defined its precision, it would be pointless to write the others.
For example, if we were told that 234.896 is only precise to the tens digit, it would suffice to write 230 because any additional digits would be meaningless.
In this case with 234.896 the last digit, '6' determines the precision since in is the last non-zero digit.

In the number 10.846, the digit that determines its precision is the last digit, which is 6. This is because precision refers to the level of detail in a measurement, and the last significant digit indicates the smallest unit of measurement being reported. Therefore, the presence of the digit 6 suggests that the value is precise to the thousandths place.
If a number is given to the true degree of precision, this is always determined by its last digit - in this case, 6.
In this case with 234.896 the last digit, '6' determines the precision since in is the last non-zero digit.

It has no precision, since there is no following number.

If a number is given to the true degree of precision, this is always determined by its last digit - in this case, 6.
Always the last number, so in this example the precision is to hundredths.
