Defined in:
app/models/typed_eav/field/decimal.rb

Overview

Decimal-typed field with optional min/max guards and optional ‘precision_scale` rounding. Declares its own `decimal_value` storage and `:min`/`:max`/`:precision_scale` `store_accessor`; the `validate :max, comparison:` macro guards against inverted bounds at field-save. `validate_range` is inherited from `Field::RangeBounded`. `Field::Percentage` extends this class to add the 0..1 invariant (chain depth becomes `Percentage < Decimal < RangeBounded < Base`).
