# `Mutare.Mutators.FloatLiteral`
[🔗](https://github.com/foxbenjaminfox/mutare/blob/v0.2.1/lib/mutare/mutators/float_literal.ex#L1)

Float-literal mutations: `x` → `x + 1.0`, `x - 1.0`, and `0.0`, deduplicated and never equal to `x`.

The float counterpart of `Mutare.Mutators.IntegerLiteral`. On by default.

Add project-specific positions to leave alone with the `:skip_arguments` option (a list of `{module, function, arity, positions}`, as in `Mutare.Mutators.IntegerLiteral`).

Filterable variants — qualify a `# mutare:ignore` filter with `:label` to suppress just one kind (`c:Mutare.Mutator.variants/0`): `zero`, `succ`, `pred`.
