MsgBox ("Data type of douValue is " & TypeName(douValue) & " with value " Like Single data type, double can also be declared using a symbol which is Hash (#) as shown below.ĭim VariableName# Sub DoubleDataTypeTest() It occupies 8 bytes of memory and has a range of values.

Double is used to store numbers with Double-precision floating-point. The Double VBA data can be used to hold both integers and fractions. MsgBox ("Data type of SingleVal1 is " & TypeName(SingleVal1) & " with value " & SingleVal1 & "Īnd datatype of SingleVal2 is " & TypeName(SingleVal2) & " with value " & SingleVal2) You can use the Exclamation mark (!) while declaring a variable as shown in the syntax below.ģ.402823E38 to -1.401298E-45 for negative valuesġ.401298E-45 to 3.402823E38 for positive values.ĭim VariableName! Sub SingleDataTypeTest() The default value is 0 and stores decimal values. This data type is used to store numbers with single-precision floating-point. Note: TypeName function will give the datatype name

MsgBox "Data type of Decvalue variable is : " & TypeName(DecValue) & " value " & DecValue Syntax: Dim vname As variant Sub DecimalDataTypeTest() This data type contains the below range of values. In order to use Decimal, you must use the CDec conversion function. This occupies 14 bytes in memory.īut variables cannot be directly declared as a decimal data type. It’s appropriate to use these types while manipulating large numbers that need a precise value. In VBA, numbers are scaled by a power of 10. That is the total number of digits and the number of digits to the right of the decimal point called a scaling factor. This is an exact numeric data type that is used for its precision. As shown below when the data type is long, an appropriate result is shown.īut when the data type is an integer, then an overflow error is thrown.

#Visual basic data type code
If you execute the above code with an integer variable, you will get an overflow error because there are 1048576 rows in Excel and Integer data type only supports till 32,767. Syntax: Dim vname As Long Sub IntDTtest() However, it occupies more memory than an integer variable which is 4 bytes. This is an alternative to an integer data type which also stores a whole integer value. MsgBox "Value of Integer variable is " & vname1 & " and " & vname2 They have a range between -32,768 to 32,767. They accept both positive values, negative values, and zero as well. An integer is one of the frequently used data types. These data types are used to store the whole integer value. Here Vname is a variable name and Byte is the data type of the variable. In case you attempt to assign invalid values, an Overflow error will be returned. Negative values and values greater than 255 are not allowed. Variables with data type Byte can store values from 0 to 255. This data type requires just one byte of memory. Let’s have a brief look at all the numeric data types. In VBA there are 7 types of numeric data types as mentioned below. Example, percentage calculation, share price, fees, bills, age, etc. These types are used to perform mathematical operations like Addition, Subtraction, etc. Numeric and Non-Numeric Data Types Numeric Data Types Data types are divided into 2 categories i.e. Data type tells the computer the type of data that needs to be stored by using a variable.
