In recent times, double layercurtainswith sheer has become increasingly relevant in various contexts. What is the difference between float and double? 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 affec... This perspective suggests that, correct format specifier for double in printf - Stack Overflow. Similarly, 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. 'double' precision - Stack Overflow.

A similar question for C/C++ (as this may be the top search engine hit): How can I get double quotes into a string literal? java - Cast Double to Integer - Stack Overflow. 494 A Double is not an Integer, so the cast won't work.
From another angle, note the difference between the Double class and the double primitive. Also note that a Double is a Number, so it has the method intValue, which you can use to get the value as a primitive int. 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 ... Additionally, what is the difference between "Double" and "double" in Java?.

That way you have consistency: Should I use double or float? A double has a much higher precision due to it's difference in size.
If the numbers you are using will commonly exceed the value of a float, then use a double. Several other people have mentioned performance isssues. That would be exactly last on my list of considerations. Correctness should be your #1 consideration.
