# `Croma.SubtypeOfFloatWithConversionFromInt`
[🔗](https://github.com/skirino/croma/blob/main/lib/croma/subtype.ex#L144)

Helper module to define float-based types.
The following members are generated by `use Croma.SubtypeOfFloatWithConversionFromInt`:

- `@type t`
- `@spec valid?(term) :: boolean`
- `@spec new(term) :: Croma.Result.t(t)`

This variant of `Croma.SubtypeOfFloat` is useful for e.g. float field in a struct that
models JSON data so that both `1.0` and `1` in JSON representation can be automatically
converted to elixir's float value by `new/1`.

Options:
- `:min` - Minimum value of this type (inclusive).
- `:max` - Maximum value of this type (inclusive).
- `:default` - Default value for this type. Passing this option generates `default/0`.

## Examples
    defmodule MyFloat do
      use Croma.SubtypeOfFloatWithConversionFromInt, min: 0.0, max: 5.0, default: 0.0
    end
