Description
It seems that it is impossible to call Math.min() and similar methods that are overloaded with the same number of primitives. The following code snippets all fail with the same exception:
minValue = Math.min(1, 2)
minValue = Math.min(1.toInteger(), 2.toInteger())
minValue = Math.min((int) 1, (int) 2)
All of these result in:
groovy.lang.GroovyRuntimeException: Ambiguous method overloading for method: min. Cannot resolve which method to invoke due to overlapping prototypes between: [float, float] and: [double, double]
This also makes it impossible to create java.awt.Color objects using RGB values, because Groovy cannot determine whether to use the float or int version of the constructor, regardless of the type of objects or casts being done.
It seems that casting on primitives doesn't work at all (or behaves like object casting).
assert 0 == (int) 0.1;
assert myFunc((int) 1.1);
def myFunc(int i) {
return true;
}
Workaround:
{
def int cast
return x;
}
assert 0 == cast(0.1);
