Dummy Math Questions
-
hello, i'm trying to cope with a couple of math calculations i need to do within my c# application. i've got two problems: first, i have difficulties translating the vocabulary to english and second, i don't know how to code it in c#. two things i require: 1. how do I get the root of n? 2. how do I calculate the reciprocal of a number? and what is the reciprocal anyway? and yes, i've been to school. but this is a long time ago. thanks for your help!

You can use Math.Pow method

Well I believe first you have to find out what reciprocal is and then start coding it. So why don;t you google?

thanks for your help on the first part. ad google: i did. but still, i don't understand what i've found. the explanations are cluttered with different approaches on how to deal with reciprocal - this is why i asked. to clear things up a little, I'd like to mention, that I'm trying to do what is written here: "To convert this value to ordinary 'Shutter Speed'; calculate this value's power of 2, then reciprocal." i'm just in need of a simple answer of somebody, who shares a household with reciprocal and c# ;)

[Douglas Adams]Here is the definition of reciprocal: http://www.mathleague.com/help/fractions/fractions.htm#reciprocal

[Douglas Adams]http://en.wikipedia.org/wiki/Reciprocal\_(mathematics) 1/X so you would take the shutter speed, square it, then divide 1 by it.

[Douglas Adams]For
reciprocalsee here [^]. And of course you don't needPowto take the square of a number, just multiply it by itself. Perhaps what you need is:ShutterSpeed = 1.0/(OriginalValue*OriginalValue);
Please note that some care must be taken when
OriginalValueapproaches zero... :)If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler. -- Alfonso the Wise, 13th Century King of Castile.

I thought he meant n-th root from number :)

Maybe you still got a divide by zero exception! :-D
