Declare Function Frac ( ByVal number As Double ) As Double

result = Frac( number )

number

返回数字或表达式的小数部分。

相当于：(number - Fix(number )).
例如，Frac(4.25)将返回0.25，Frac(-1.75)将返回-0.75.对于整数类型，始终返回值0.

Frac一元Operator可以用用户定义的类型重载。

Print frac(10.625)  ''将打印0.625
Print frac(-10.625) ''将打印-0.625

• 在-lang qb 方言中，此运算符无法重载。
