toString()
calls on objects of a class extending Number
.
Such calls are usually incorrect in an internationalized environment and some locale specific formatting should be used instead.
Example:
void print(Double d) {
System.out.println(d.toString());
}
A possible way to fix this problem could be:
void print(Double d) {
System.out.printf("%f%n", d);
}
This formats the number using the default locale which is set during the startup of the JVM and is based on the host environment.
