How does one raise an integer to a power?
This is stupid!!!!
I have looked everywhere (in books, google, online....) to find out how to raise a number to a power and I can't find it!!! For example: given x = 10 y = x ^ 2; y would then be 100 (10 squared is 100). Why can't I find such a basic operation!? Steve |

Sorry,

Math.Pow(x, y)

It might be useful to point out that the x stands for the number
to be raised and that the y stands for the power to which the x is raised. i.e., the return value of Math.Pow(x, y) is the number x raised to the power y. http://msdn2.microsoft.com/en-us/lib....math.pow.aspx Juan T.

Unlike VB, C# has no exponentiation operator built into the language. You
have to use the Math class (Math.Pow). -- David Anton www.tangiblesoftwaresolutions.com Instant C#: VB to C# converter Instant VB: C# to VB converter Instant C++: C#/VB to C++ converter C# Code Metrics: Quick metrics for C# "Steve Kershaw" wrote: > This is stupid!!!! > > I have looked everywhere (in books, google, online....) to find out how > to raise a number to a power and I can't find it!!! > > For example: > > given x = 10 > y = x ^ 2; > y would then be 100 (10 squared is 100). > > Why can't I find such a basic operation!? > > Steve > > |

Which is where it should be.

Using that same argument you could say that we should also have Logical.Or
instead of || and Math.Multiply instead of *. It's debatable what should be built in operators and what shouldn't. -- David Anton www.tangiblesoftwaresolutions.com Instant C#: VB to C# converter Instant VB: C# to VB converter Instant C++: C#/VB to C++ converter C# Code Metrics: Quick metrics for C# "clintonG" wrote: > Which is where it should be. > > <%= Clinton Gallagher > NET csgallagher AT metromilwaukee.com > URL http://www.metromilwaukee.com/clintongallagher/ > > > "David Anton" <DavidAnton@discussions.microsoft.com> wrote in message > news:F48F9C0C-77D9-432D-A7B8-2E30920528D9@microsoft.com... > > Unlike VB, C# has no exponentiation operator built into the language.

Not necessarily... In computer science, powers aren't a basic operation. In fact, they require careful logic and could easily be ineffient. This logic should be placed in a function so software engineers can see the source code and calculate the complexity should they decide to implement a better version.

Also, using a function for a basic operation such as or is extremely inefficient because of function call overhead
