Is it true significant digits are the number of digits that reflect the precision of a measurement or number?
No, it is not true. They reflect the precision of the number in the context of its use. If required to calculate the population density of Greater London in 2011, I would use the population in millions - not because that is the limit of the accuracy of the census results but because greater accuracy does not add significant value to the precision of the population density.
What is a precision number?
A Precision Number is the number of digits in a number.
Significant digits are the number of digits that reflect the precision of a measurement or number?
Not necessarily. I measure my height to 3 sig figs (for example 178 cm), but I may choose to report is as 180 cm (to 2 sf).
How does the precision of a calculated answer compare to the precision of the measurements use to obtain it?
the precision of the answer must have the same number of significant digits as the measurement with the least significant digits- the site explains the rules and how to identify significant digits
How many significant figures should be in the answer obtained by adding 0.04 31.2 and 100.0?
The answer is limited to the number with the fewest digits of precision (digits after the decimal point). (2 digits of precision)
What do you call the number of a digit that reflects the precision of a calculation?
significant digits
How is the precision of a calculated result related to the precision of the measurements used in the calculation?

What is the term for eliminating digits that are not significant?
The term for eliminating digits that are not significant is called rounding or truncating. This process involves reducing the number of digits in a calculation to match the precision of the measurement.

What is the precision of a number?
The number of digits in a number is known as precision of a number. Depending on the precision required, the number is quantized to give the final number.

What does full precision mean?
Accuracy means how close you are to the target.(percentage error from target) Precision means how close you can determine what the target is;how many digits of your answer are reliably correct.(ability to measure in miles, feet, or inches). Full precision means the particular number you have has all or more than all of its digits correct needed to complete the calculation you are working on.

Significant digits are the number of digits that reflect the precision of a measurement or number True or false?
false.!!!I would have to disagree with this answer!! The member did not explain themselves!! I would have to say the answer is "TRUE"!!! Any feedback on this topic? Anyone care to respond, have discussion?I am also sure that the answer is true; see the link bellow.
Are The number of significant digits in a double variable is up to 15?
The maximum number of significant digits in value belonging to the double type is 15. The maximum number of significant digits is called the precision.
