What is the guaranteed accuracy of multiplication operator for double values in java?
For example, 2.2 * 100 is 220.00000000000003, but 220 is a double number. 220.00000000000003 is the next double after 220.
The multiplication is working fine, but
2.2cannot be represented exactly as a double. The closest doubles are:Some software will print the latter value as
2.2, but that doesn’t mean it’s exact. It just means it’s treated as “close enough”.
