problem in rounding the double value

[anu sav]

Hi,
i want the double value rounded up to the nearest 0.05
e.g., if input= 10.37 then output= 10.35
if input=10.33 then output=10.35
can anybody help for this logic ?

Thanks

double d = 10.33;
System.out.println(Math.round(d * 20d) / 20d); // Prints 10.35
d = 10.37;
System.out.println(Math.round(d * 20d) / 20d); // Prints 10.35

That is not rounded up.

Remember all floating-point arithmetic, including rounding, is subject to errors of imprecision.
