What is a precision number?
A Precision Number is the number of digits in a number.
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
Can significant digits be written in a fraction form?
The significant digits of a number represent a count of digits and so are represented by an integer. Any integer can be written in fractional form.
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)
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.
How many digits of pi do you need to calculate the circumference?
you only need 3.14 for the circumfrence of a circle

How many digits of pi would it take to find the circumference of the known universe with the accuracy of one proton?
My guess is fewer than 100.
What is pi in decimal from?
Pi is an irrational number, a decimal that won't stop. It has been calculated to ten trillion digits, which is kind of silly because just 39 digits are enough to calculate the circumference of a circle the size of the observable universe with an error no larger than the radius of a hydrogen atom.To five places, it's 3.14159

How is the precision of a calculated result related to the precision of the measurements used in the calculation?
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 sigificant digits does 0.050200?
Assuming that the last two digits are indicators of precision, there are 5 significant digits.
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.
How do you find the least precision?
Start by measuring accurately, then just remove digits until you have the precision you want.
