WebAug 27, 2014 · Aug 27, 2014 10:56 AM. It seems that the numerical calculation in Mathcad only can process 16 significant figures, such as 123.4567890123456 or 123456789.0123456, and when the number have more significant figures, MC will round it to 16 or 17. I knew that symbolic calculation could process up to 250 decimal. WebFinding the percent error involves three steps: Calculate the error, which is the Estimate – Correct Value. Divide by the Correct Value. Multiply by 100 to produce a percentage. When calculating this statistic, some fields of study retain the plus or minus values to indicate whether the Estimate is above or below the Correct value.
WebJan 20, 2010 · 1. @David: give them an example where floating point numbers are exact, such as adding 0.25 multiple times. The result will be exact until you overflow the mantissa, because 0.25 is 1/ (2^2). Then try the same thing with 0.2 and you will get the problems, because 0.2 isn't representable in a finite base-2 number.
