I would like to have the closest number below 1.0 as a floating point. By reading wikipedia\'s article on IEEE-754 I have managed to find out that the binary representation for 1.0 is 3FF0000000000000
System.out.开发者_StackOverflow中文版println(2.14656); 2.14656 System.out.println(2.14656%2); 0.14656000000000002
I\'m wondering if a number is re开发者_开发百科presented one way in a floating point representation, is it going to be represented in the same way in a representation that has a larger size.
This question already has answers here: Closed 12 years ago. Pos开发者_开发技巧sible Duplicate: Which is the first integer that an IEEE 754 float is incapable of representing exactly?
Why does this: int main(v开发者_StackOverflow社区oid) { short w = 30; return1.2 * w; } return 35?If you want to get more suitable result, try the following:

While learning about precision in floating point arithmetic and different methods to avoid it (using a conjugate, taylor series,...) books frequently mention the subtraction of two very similar number
As (hopefully) most of you know, floating point 开发者_开发问答arithmetic is different from real number arithmetic. It\'s for starters imprecise. Many numbers, especially decimals (0.1, 0.3) cannot be
I have an sql: SELECT Sum(Field1),开发者_开发问答 Sum(Field2), Sum(Field1)+Sum(Field2) FROM Table
I was doing some unit testing at work and a peculiar error popped up for one of the assertions. Note that expectedValue and actualValue are both doubles.
