I noticed in latest IntelliJ IDEA 2017.3.3 it has started to flag the following code as an red error, as if it was a compile error:
float a = 1
float b = 2
float c = a + b
It says loss of precision when assigning to c. It is true per http://docs.groovy-lang.org/latest/html/documentation/core-syntax.html#_math_operations that a float + float is a double, for whatever (probably historical) reason. But this is not supposed to be a compiler error in compile static mode? It seems as worst case this should be a warning. But even if it's a warning, is this inappropriate Groovy code? Should c always be of type double? Should float be avoided? Would a cast always be appropriate style?
