Academic Skills AdviceDecimals Places & Significant figures. Rounding Decimals: Sometimes you could be asked to round a number to a certain number of decimal places (or to a whole number). This does not mean that you move the decimal point. You leave the decimal point where it is but get rid of some numbers from the end. The method is to look at the next number after the one you want to stop ...
Counting Significant Figures
Zeroes placed after other digits but behind a decimal point are significant; 7.90 has three significant digits. Zeroes at the end of a number are significant only if they are behind a decimal point as in (c). Otherwise, it is impossible to tell if they are significant. For example, in the number 8200, it is not clear if the zeroes are significant or not. The number of significant digits in ...

2) Trailing zeros after the decimal point should be written in scientific notation. EXAMPLE 0.0007700 = 7.700 x 10-4 . 0.0007700 ≠ 7.7 x 10-4. 3) Leading zeros should not be written in scientific notation. EXAMPLE 0.000 02 = 2 x 10-5. 0.000 02 ≠ 00002 x 10-5. 4) Captive zeros (zeros between non-zero numbers) should be written in scientific ...
