AttemptedNegativeZero

-0 is the same as 0. For the floating-point negative zero, use -0.0.

## The problem

Because `0`

is an integer constant, `-0`

is an integer, too. Integers have no
concept of “negative zero,” so it is the same as plain `0`

.

The value is then widened to a floating-point number. And while floating-point
numbers have a concept of “negative zero,” the integral `0`

is widened to the
floating-point “positive” zero.

To write a negative zero, you have to write a constant that is a floating-point
number. One simple way to do that is to write `-0.0`

.

## Suppression

Suppress false positives by adding the suppression annotation `@SuppressWarnings("AttemptedNegativeZero")`

to the enclosing element.
