每个函数都可以将表达式（表达式：算术或逻辑运算符、常数、函数和字段名称、控件和属性的任意组合，计算结果为单个值。表达式可执行计算、操作字符或测试数据。）强制转......
Dim MyDouble1, MyDouble2, MySingle1, MySingle2
' MyDouble1, MyDouble2 are Doubles.
MyDouble1 = 75.3421115: MyDouble2 = 75.3421555
MySingle1 = CSng(MyDouble1)
' MySingle1 contains 75.34211.
MySingle2 = CSng(MyDouble2)
' MySingle2 contains 75.34216.
CStr 函数
此示例使用 CStr 函数将数值转换为 String 值。
Dim MyDouble, MyString
MyDouble = 437.324 ' MyDouble is a Double.
MyString = CStr(MyDouble)
' MyString contains "437.324".
CVar 函数
此示例使用 CVar 函数将表达式转换为 Variant 值。
Dim MyInt, MyVar
MyInt = 4534 ' MyInt is an Integer.
MyVar = CVar(MyInt & "000")
' MyVar contains the string 4534000
