However, in most cases, float and double seem to be interchangeable, i.e I have to calculate some floating point variables and my colleague suggest me to use bigdecimal instead of double since it will be more precise Using one or the other does not seem to affec.

The 53 bits of double s give about 16 digits of precision
The 24 bits of float s give about 7 digits of precision.
L specifies that a following a, a, e, e, f, f, g, or g conversion specifier applies to a long double argument The same rules specified for fprintf apply for printf, sprintf and similar functions. 494 a double is not an integer, so the cast won't work 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. Long double vs double i am unable to understand the difference between between long double and double in c and c++ 39 this question already has answers here Double vs double in java [duplicate] (7 answers) difference between decimal, float and double in.net
Different double and double in comparison in a sample java program for one of my labs, i have two different methods taking double and double parameters respectively.
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. 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?
