Subject float math in Groovy and IntelliJ
Date Tue, 23 Jan 2018 22:16:26 GMT
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
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?
