ITLab.Template.DevPack.Structs

Provides immutable value structs for domain primitives requiring strict precision or type safety.

Tipo	Nome	Responsabilidade
Struct	RoundedDouble	Immutable double wrapper always rounded to 2 decimal places, with implicit conversions to/from double

Como usar

// Assign from a raw double — rounding is applied automatically.
RoundedDouble price = 19.999;  // stored as 20.00

// Implicit conversion back to double for arithmetic.
double total = price * quantity;

// Safe equality comparison without floating-point drift.
Assert.Equal((RoundedDouble)10.005, (RoundedDouble)10.01);

O que não fazer

• Do not use RoundedDouble for scientific or high-precision calculations that require more than 2 decimal places.
• Do not bypass the struct by casting to double before performing comparisons.

Extensão pelo produto

• Products can follow the same pattern to introduce other precision-controlled value structs (e.g. RoundedDecimal, PositiveInt).
