How to avoid "Math." in front of every math function in C#?

Question

I'm writing some C# heavy in mathematics. Many lines in sequence using plenty of abs(), min(), max(), sqrt(), etc. Using C# is the plain normal way, I must preface each function with "Math." For example

double x = Math.Min(1+Math.Sqrt(A+Math.Max(B1,B2)),
           Math.Min(Math.Cos(Z1),Math.Cos(Z2)));

I'd rather write code like in C:

double x = min(1+sqrt(A+max(B1,B2)), min(cos(Z1), cos(Z2)));

This is easier to read and looks more natural to scientists and engineers. The normal C# way hides the good bits in a fog of "Math."

Is there a way in C# to do this?

After some googling I found an example which lead me to try

using min = Math.Min;
...
double x = min(a,b);        

but the "using" statement produced an error, "System.Math.Min(decimal,decimal) is a method but is used like a type" but otherwise this looked like a good solution. (What is 'decimal', anyway?)

Answer 1

If you really care that much, you can write your own method

private int min(int a, int b)
{
    return Math.Min(a, b);
}

if you're ambitious, you can look into doing this with generics

Also, if you want to increase clarity, you can create a new, descriptive variable for each meaningful part, instead of your expression, instead of doing everything inline.

double piece2 = 1+Math.Sqrt(A+Math.Max(B1,B2));
double piece1 = Math.Min(Math.Cos(Z1),Math.Cos(Z2))
double x = min(piece1, piece2);

The only reason I'm naming things piece2 and piece2, is because I don't actually know what your expression is supposed to calculate. In practice, you should have more meaningful names such as velocity, or incomeTaxPercentage
