LogicalCalculation class

dart中逻辑计算类-只涉及简单加减乘除

Constructors

LogicalCalculation.new({int point = 0, num? initValue})

默认构造函数 point 默认计算精度及返回小数点位数 initValue 初始值

Properties

no setter, inherited

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

totalValue → num

no setter

Methods

add(num val) → LogicalCalculation

加法运算

minus(num val) → LogicalCalculation

减法运算

noSuchMethod(Invocation invocation) → dynamic
