I\'m using Visual C++ 2008 Express Edition and when i debug code: 开发者_StackOverflow社区double x = 0.2;
I want to print numbers to a file using the stl with the number of decimal places, rather than overall precision.
I am aware of how floating point precision works in the regular cases, but I stumbled on an odd situation in my C# code.
Is there a way to set the \"minimum\" number of decimal places that a std::ostream will output? For example, say I have two unknown double variables that I want to print (values added here for the sa
The documentation states: \"Precision can range from 开发者_如何学Python1 to 38. Scale can range from -84 to 127\".
I have a TDateTime variable which is assigned a value at runtime of 40510.416667.开发者_开发百科 When I extract the time to a TTime type variable using the Frac function, it sets it to 0.41666666666.
I\'m just pondering about whether or not it\'s possible to create one\'s own data type? So if y开发者_如何学JAVAou need more precision, that\'s not supported by one of the basic types, you could just
I\'ve read about the difference between double precision and single precision. However, in most cases, float and double seem to be interchangeable, i.e. using one or the other does not seem to affect
When I call get_d() on a MPQ v开发者_StackOverflow中文版ariable in the GMP library, I only get at most six digits.
I wish to round a floating point number to set precision and return the result from a function. For example, I currently have the following function:
