No, it does not. That is not a value that a double
can represent exactly.
You can easily verify that with this code:

QUESTION
I'm trying to round up the Digdecimal by using RoundingMode, but in my test, bd is still 6.45607, why setScale() doesn't work?
...ANSWER
Answered 2021-Jun-01 at 22:50From the Javadoc for setScale
.
Note that since BigDecimal objects are immutable, calls of this method do not result in the original object being modified, contrary to the usual convention of having methods named setX mutate field X. Instead, setScale returns an object with the proper scale; the returned object may or may not be newly allocated.

QUESTION
I know this question has been asked many times but I'm stuck and I don't know what the correct solution should be. I'm writing a program and there's a lot of numbers multiplication. The result must be rounded to 2 decimal places but sometimes the result is not correct.
For example: I have two doubles v1=99.338 and v2=732.5.
I want to multiply them and have the result rounded to 2 decimal places. The correct result is 72765.085 so after rounding it should be 72765.09 however in computer the result is 72765.08499999999 and all the rounding methods give 72765.08 which is obviously wrong.
For example
double x= v1 * v2; //x=72765.08499999999
ANSWER
Answered 2021-May-31 at 10:13First of all 99.337 * 732.5 = 72764.3525
, and NOT 72765.085
