Suspicious integer division assignment
Reports assignments whose right side is a division that shouldn't be truncated to integer.
While occasionally intended, this construction is often buggy.
Example:
int x = 18;
x *= 3/2; // doesn't change x because of the integer division result
This code should be replaced with:
int x = 18;
x *= 3.0/2;
- By ID
Can be used to locate inspection in e.g. Qodana configuration files, where you can quickly enable or disable it, or adjust its settings.
SuspiciousIntegerDivAssignment
In the inspection options, you can disable warnings for suspicious but possibly correct divisions, for example, when the dividend can't be calculated statically.
void calc(int d) {
int x = 18;
x *= d/2;
}
