Scientific Notation in C #

Question

How to assign a number that is in scientific notation for a variable in C #?

I am looking to use Plancks Constant which is 6.626 X 10 ^-34

This is the code that I have is incorrect:

Decimal PlancksConstant = 6.626 * 10e-34; 

Answer 1

You should be able to declare PlancksConstant as double and multiply 6.626 by 10e-34, for example:

 double PlancksConstant = 6.626e-34

Answer 2

You can set it like this (note the M suffix for the decimal type):

 decimal PlancksConstant = 6.626E-34M; 

But it will be effectively 0 , because you cannot imagine a number with a value less than 1E-28 as decimal .

So you need to use double instead and just define this:

 double PlancksConstant = 6.626E-34;
