I have a constant for pi in my code: const float PI = acos(-1); Would it be better to declare it as a double?An answer to another question on this site said floating point operations aren\'t exactly
Here is开发者_如何学运维 my string 20.0e-6 I\'m parsing it like String Ans=Double.Parse(\"20.0e-6\")
I\'m revisiting a question (How to test if numeric conversion will change value?) that as far as I was concerned was fully solved. The problem was to detect when a particular numeric value would overf
I\'m looking for a C# equivalent to Java\'s Double.longBitsToDouble method. I have a double value stored in a ulong and I want those bits to be converted 开发者_开发知识库to represent a double. Is the
Suppose I\'m in an environment whose only float type is (say) 32 bits wide, and I want to do some calculations with 64-bit floats.
my caller-code looks like this: NSDictionary *myDictionary = [NSDictionary dictionaryWithObjectsAndKeys:
Hey all, I need to compare a double inside开发者_JAVA技巧 an if statement. If the double has no value/is equal to zero, it should do nothing. Otherwise it should do something.
i want to use the sqrt implementation of fdlibm. This implementation defines (according to the endianess) some macros for accessing the lower/upper 32-bit of a double) in the following way (here: only
What is the correct format specifier for double in printf? Is it %f or is it %lf? I believe it\'s %f, but I am not sure.
Here is the simplified code: i开发者_Go百科nt i = 1; double a = i; double b = i; Is it guarantied that a == b is true?Yes. 32-bit integers can be represented exactly as 64-bit floating point number
