Help:Math.Cos not accurate enough(C#)

[Deathnote]

---

Need help from the masters again...Hope they see this

So im doing a bpo project wherein accuracy is important...the problem is when i use the math.cos function it only gives me a double return value...

in excel it works fine..here is my function in excel

=0.025*COS(1/180*PI())

it gives me the correct and precise value of 0.024996192

but when i do it in c#

decimal answer= 0.025 * Convert.ToDecimal(Math.Cos(1 / 180 * Math.PI))

it gives me a round off value of .025.. T.T....mga master pls help me

Try:

Double answer = 0.025D * Math.Cos(1D / 180 * Math.PI);

Gamit ug double bai kay mas dako ug range.

oo bai. read ug .net datatypes. compare it with others, pila ang precission sa uban. And besides ang Math.Cos() returns and accepts double types. be precise ug gamit sa datatypes labi na expect ka ug gagmay na values.
