SerializedProperty.numericType

説明

Return the precise type for Integer and Floating point properties. (Read Only)

The propertyType property classifies all supported Integer types as SerializedPropertyType.Integer, and both single and double precision Float types as SerializedPropertyType.Float. This property exposes the precise type, for example SerializedPropertyNumericType.UInt8 and SerializedPropertyNumericType.Double, and is more efficient than using the string-based type property. For enum properties (SerializedPropertyType.Enum) it returns the underlying type. For non-numeric types it returns SerializedPropertyNumericType.Unknown.
