Good afternoon:
I'm making a Nominal Rate formula for that they gave me this formula:
= (((TEA + 1) ^ (1/12)) - 1) * 12
decimal x = 3.141592654M ;
double pi = (double) x ;
dtorequest.Tasa = Convert.ToDecimal((Math.Pow((Convert.ToDecimal(pi) + 1), (1 / 12))) - 1) * 12;//40;
Since my dtorequest.Tasa is a decimal variable, I get a decimal error. Could you help me please?
An example:
The error that comes out of Overflow when casting is because the Decimal is bigger than the Double can represent.
On the other hand, unless you are doing a graph with some curve, it sounds strange to me that the PI number is in a Financial formula:)
You do not need to define your own pi but instead use it:
Math.PI
Also in the following expression (1/12) you should use a 1.0 which is a double otherwise it will be a whole division and the result will not be as expected
The complete line would be
dtorequest.Tasa = Convert.ToDecimal((Math.Pow((Math.PI + 1),(1.0/12)) - 1) * 12)
