You should always try and use the data type that uses the smallest number of bytes.All variables must have an associated data type which determines what data can be stored in it. Array (a) array of Integer, Double, String(av) array as a single variant Boolean (True or False / 0) (...
浮点类型数值赋值给整数类型变量时,自动转换为整数类型,并按四舍五入规则取整(x.5向下取整)。 DimiAsIntegeri =1.23'i -> 1i =0.9'i -> 1i =1.5'i -> 1 字符串表示的纯数字→数值 使用文本表示的纯数字,表达式和赋值语句中自动转换为数字。以下以Double类型变量为例。 DimdAsDoubled ="123"'d -> ...
(2)关于Range.Value2: The only difference between this property and theValueproperty is that theValue2property doesn't use theCurrencyandDatedata types. You can return values formatted with these data types as floating-point numbers by using theDoubledata type. 2 基于指定列,保留最后一行的数据,...
Keep in mind that Integer will always round your decimals to the nearest integer, which means you might get some strange results if you’re not expecting them. If you need more precision, use Double. There aremany other numerical VBA data types.But you should be able to handle just about...
Subtest()Dim vArray As Variant,dValue As Double Dim iRow As Integer,iCol As Integer vArray=Range("A1:C10000").Value2 'read all the values at once from the Excel cells,put into an array For iRow=LBound(vArray,1)ToUBound(vArray,1)For iCol=LBound(vArray,2)ToUBound(vArray,2)dValue=...
The Integer data type takes up 2 bytes of memory, which means it can store values from -32,768 to 32,767. This is useful for small numbers that do not require decimal places and can save memory space compared to other data types like Double or Long. Range: As mentioned earlier, the ...
Double is useful when you need to store values containing a high degree of fractional precision. String is used for storing text. Object is for storing ranges; such as application, workbook, worksheet, and range. It’s not to say that you should never use Variant as a data type. If you...
官方文档定义:A special data type that can contain numeric, string, or date data as well as user-defined types and the special values Empty and Null. The Variant data type has a numeric storage size…
Converting a Date Value to a Numeric Data type: Dates can be converted to and from numeric data types. You can see some examples below: Although you can convert integers to dates, but it can’t be done vice versa. Dates can only be converted to double and single data type: ...
除了Variant 之外,支持的数据类型包括 Byte、 Boolean、 Integer、 Long、 Single、 Double、 Currency、 Decimal、 Date、 Object 和String。 使用Dim 语句声明特定类型的变量,例如: VB 复制 Dim X As Integer 此语句声明变量 X 是整数 -32,768 和 32,767 之间的整数。 如果您尝试将 X 设置为此范围之外的...
