![]() ![]() Convert the fraction to a decimal number. Multiply by 100 to get percent value: 0.25 × 100 25. Use division to convert the fraction to a decimal: 1/4 1 ÷ 4 0.25. If (Math.Abs(1.0 / a_r - value) (1, a_r) Įlse if (Math.Abs(b_r / (a_t * b_r + 1. Two Steps to Convert a Fraction to a Percent. Percentages are computed by multiplying the value of a ratio by 100. This table can be used as a reference for fractions commonly. Int c = (int)Math.Round(1 / (f1 - Math.Truncate(f1))) For example, 35 is equivalent to the decimal 0.35, or the fractions. The calculator provided automatically converts the input percentage into a decimal to compute the solution. The result of the calculation in percent is 2.5/10100 25. ![]() Private void button1_Click(object sender, EventArgs e)įor (int i = 0 i getFraction(double value, double tolerance = 0.02)ĭouble f1 = 1 / (f0 - Math.Truncate(f0)) To convert a Percent to a Fraction follow these steps: Step 1: Write down the percent divided by 100 like this: percent 100 Step 2: If the percent is not a whole number, then multiply both top and bottom by 10 for every number after the decimal point. The resulting fraction is reduced and is the best approximation among all fractions with the same or lower denominator. The code gives you the best rational approximation within the specified tolerance it can find. (I know that 3 letter variable names are not good but I can't think of good names for them :-/ ) Nevertheless I have cleaned it up a little. I failed to come up with an iterative (or recursive) approach in resonable time. By limiting the depth to three I got a reasonable approximation. I have tried to satisfy your requirement by using continued fractions. Often to convert a percent value to a decimal value we can just place the percentage on a denominator of 100 and remove the sign.
