Is 0 a significant figure

Answer 1

When it is between non-zero digits, e.g.: 504 or 2005When there is one or more zeros after the last non-zero digit AFTER the decimal point, e.g.: 3.40

When there are zeros after the last non-zero digit in a whole number, one or more zeros MAY be significant, e.g.: 500. But if you have to guess, you should consider such zeros to be non-significant.

Answer 2

Zeroes are significant digits only when they separate or follow non-zero figures. When they are to the right of the decimal point, they only establish an exponent when they precede the first non-zero digit.

Examples : in 0.00096, the only significant digits are 9 and 6.

Examples : in 0.0906, the zero between the 9 and the 6 is significant.

Examples : in the number 0.090600, the last three zeroes are significant, but not the first two.

In the final example, the zeroes after the 6 represent a measured quantity less than 1 for each of the values, and are therefore significant.

Answer 3

yes as in 0,5,7,1,3 and 8

In integers, leading zeros are not significant, that 09 is the same as 009, 0009, etc. all of which really mean 9. However, trailing zeros in integers are very very significant. 9 is not the same as 90 which is not the same as 900, which is not the same as 9000 and so on.

In decimal math, trailing zeros are not significant, that 0.90 is the same as 0.90, 0.900, etc. all of which really mean 0.9. However, leading zeros in decimal math are very very significant. 0.9 is not the same as 0.09 which is not the same as 0.009, which is not the same as 0.0009 and so on.

Answer 4

Before any non-zero numbers:

.000545

After any non-zero numbers (unless specified by a decimal at the end or a repeating symbol):

185,000

In these two cases, the zeros are just placeholders, and are only there to show where the rest of the digits lie.

Answer 5

The zero after a decimal point considered as significant digit because that is the defined, accepted convention.

12 is 12 +/- 0.5

12.0 is 12 +/- 0.05

12.00 is 12 +/- 0.005

12.000 is 12 +/- 0.0005

etc.

Answer 6

In scientific notation, zeros to the left of a non-zero digit are not considered significant figures. So in that sense, 0 is generally not considered a significant figure.

Answer 7

When it comes at the beginning of a number, as in 0.54.

Answer 8

When it is to the right of the decimal point.

When it is between two other significant digits.

Answer 9

Zeros appearing anywhere between two non-zero digits are significant. Trailing zeros in a number containing a decimal point are significant.

Answer 10

A zero is significant if it comes between other significant figures, and when it is located after a decimal point.
