How can I convert fraction to double or decimal?

Question

Case:

double x = Math.Pow(Convert.ToDouble(0.07003 + 1 ),(1/12));
Console.WriteLine(x);

Output:

1

The above output is incorrect, because the result of x is 1 instead of 1.005657

How to convert 1/12 in a format that it gives fractional value and is accepted by Math.Pow() .

And the real problem is division of 1 by 12 ( 1/12 ) which gives value 0 (instead of 0,083333... ).

Answer 1

Try this:

double x = Math.Pow(Convert.ToDouble(0.07003 + 1 ),(1/12d));

This makes 12 a double which makes the result of 1/12 a double. So instead of getting 0 from that division the result will be 0.0833333333333333 .

Answer 2

The literals 1 and 12 are both integers, so 1/12 is an integer division, giving an integer result (0). Change at least one literal to double or decimal to perform a floating point division.

To make a number literal a double , add decimal places (eg 1.0 ) or 'D' suffix ( 1D ). To make it a decimal, add 'M' suffix ( 1M ).
