Here's one way to round any Double or Int (including negative numbers) to a given number of significant figures: func round(_ num: Double, to places: Int) -> Double { let p = log10(abs(num)) let f = pow(10, p.rounded() - Double(places) + 1) let rnum = (num / f).roun...
I have then been able to target my search further, to determine whether my first significant number has any 'problematic' zeros in the immediate digits after it. If there are any, then I set a Boolean variable to 'true' and then in a separate function create further text strings of my ...
Rounding numbers to Significant FiguresRounding to significant figures is different from rounding to decimal places. The first significant figure is the first non-zero digit a number has. The second significant figure is the digit after the 1st significant figure. The third significant figure is the...

How do you tell Excel to round to a specific number of significant figures without having to use exponential notation? This Excel formula will do the trick:=ROUND(value,sigfigs-(1+INT(LOG10(ABS(value)))value :: the number you wish to round. sigfigs :: the number of significant figure...
102,000 has 3 significant digits. 6. When numbers are in scientific notation, disregard the power of ten and use the above rules on the decimal number only. 3.8 X has 2 significant digits. 3.08 X has 3 significant digits. 3.080 X has 4 significant digits. Multiplication and Division To ...

To apply significant figures in calculations, the following rules should be followed: a. Addition and subtraction: The result should be rounded to the least precise decimal place identified in the original numbers. b. Multiplication and division: The result should contain the same number of signific...
Express the base-10 logarithm of a value using the same number of significant figures as is present in the normalized form of that value. Similarly, for antilogarithms (numbers expressed as powers of 10), use the same number of significant figures as are in that power. (If you are in a...
