- Integer division: How do you produce a double? - Stack Overflow
double d = ((double) num) denom; But is there another way to get the correct double result? I don't like casting primitives, who knows what may happen
- java - Double vs. BigDecimal? - Stack Overflow
There are two main differences from double: Arbitrary precision, similarly to BigInteger they can contain number of arbitrary precision and size (whereas a double has a fixed number of bits) Base 10 instead of Base 2, a BigDecimal is n*10^-scale where n is an arbitrary large signed integer and scale can be thought of as the number of digits to move the decimal point left or right It is still
- How can I truncate a double to only two decimal places in Java?
1 In this solution, this will TRUNCATE a double to only two decimal places This solution will not ROUND OFF the double value
- Correct format specifier for double in printf - Stack Overflow
Format %lf in printf was not supported in old (pre-C99) versions of C language, which created superficial "inconsistency" between format specifiers for double in printf and scanf
- What does the !! (double exclamation mark) operator do in JavaScript . . .
The double "not" in this case is quite simple It is simply two not s back to back The first one simply "inverts" the truthy or falsy value, resulting in an actual Boolean type, and then the second one "inverts" it back again to its original state, but now in an actual Boolean value That way you have consistency:
- Why would you use float over double, or double over long double?
I understand that float has a smaller range than double making it less precise, and from what I understand, long double is even more precise (?) So my question is why would you want to use a variable that is less precise in the first place? Does it have something to do with different platforms, different OS versions, different compilers?
- How do I print a double value with full precision using cout?
In my earlier question I was printing a double using cout that got rounded when I wasn't expecting it How can I make cout print a double using full precision?
- How do I convert a double into a string in C++? - Stack Overflow
The easiest way to convert a double into a string is via std::to_string but unfortunately it's pretty broken up to C++23 (e g it poorly handles small and large in magnitude numbers due to fixed format) although it may be fixed in C++26
