Boolean Use the Boolean Data Type (Visual Basic) to contain two-state values such as true/false, yes/no, or on/off. Depends on implementing platform True or False Byte Use the Byte data type to contain binary data. The default value of Byte is 0. 1 byte 0 through 255 2 bytes 0 through 65535 8 bytes 0:00:00 (midnight) on January 1, 0001 through 11:59:59 PM on December 31, 9999 Char Use the Char data type when you need to hold only a single character and do not need the overhead of String. Date Use the Date data type to contain date values, time values, or date and time values. 0 through +/79,228,162,514,264,337,593,543,950,335 (+/-7.9...E+28) † Decimal The Decimal data type provides the greatest number of significant digits for a number. 16 bytes with no decimal point 0 through +/7.9228162514264337593543950335 with 28 places to the right of the decimal -1.79769313486231570E+308 through -4.94065645841246544E-324 † for Double The default value of Double is 0. 8 bytes negative values; 4.94065645841246544E-324 through 1.79769313486231570E+308 † for positive values Integer (Int32) The Integer data type provides optimal performance on a 32-bit processor. The other integral types are slower to load and store from and to memory. 4 bytes Long (Int 64) Use the Long data type to contain integer numbers that are too large to fit in the Integer data type. 8 bytes -2,147,483,648 through 2,147,483,647 -9,223,372,036,854,775,808 through 9,223,372,036,854,775,807 Object The Object data type can point to data of any data type, including any object instance your application recognizes. Use Object when you do not know at compile time what data type the variable might point to. 4 bytes on 32-bit platform 8 bytes on 64-bit platform Any type can be stored Sbyte Use the SByte data type to contain integer values that do not require the full data width of Integer or even the half data width of Short. 1 byte -128 through 127 Short (Int 16) Use the Short data type to contain integer values that do not require the full data width of Integer. 2 bytes -32,768 through 32,767 (signed) 4 bytes -3.4028235E+38 through -1.401298E45 † for negative values; 1.401298E-45 through 3.4028235E+38 † for positive values Single Use the Single data type to contain floating-point values that do not require the full data width of Double. String Use the String data type to hold multiple characters without the array management overhead of Char(), an array of Char elements. Depends on implementing platform 0 to approximately 2 billion Unicode characters UInteger (UInt 32) The UInteger data type provides the largest unsigned value in the most efficient data width. 4 bytes 0 through 4,294,967,295 8 bytes 0 through 18,446,744,073,709,551,615 2 bytes 0 through 65,535 ULong (UInt 64) Use the ULong data type to contain binary data too large for UInteger, or the largest possible unsigned integer values. Ushort (UInt16) Use the UShort data type to contain binary data too large for Byte. User-defined Holds data in a format you define. The Structure statement defines the format. Depends on implementing platform Each member of the structure has a range determined by its data type and independent of the ranges of the other members
