Overview

Package null contains types which can be NULL in some storage engines.

The aim is to import database/sql to avoid the dependency on SQL. Null values can occur everywhere hence we want to keep the deps minimal.

type Decimal 

type Decimal struct {

	Scale        int32  // Number of digits after the dot

	// contains filtered or unexported fields
}

Decimal defines a container type for any MySQL/MariaDB decimal/numeric/float/double data type and their representation in Go. It can store arbitrary large values. Decimal does not perform any kind of calculations. Helpful packages for arbitrary precision calculations are github.com/ericlagergren/decimal or gopkg.in/inf.v0 or github.com/shopspring/decimal or a future new Go type. https://dev.mysql.com/doc/refman/5.7/en/precision-math-decimal-characteristics.html https://dev.mysql.com/doc/refman/5.7/en/floating-point-types.html
