Integer data types in LabVIEW include both signed and unsigned types in one (1) byte, two (2) byte, four (4) byte, and eight (8) byte lengths. They are as follows:

Type Name Range Representation Icon Terminals
U8 Unsigned Byte Integer (0 to 255) U8 U8 U8
U16 Unsigned Word Integer (0 to 65,535) U16 U16 U16
U32 Unsigned Long Integer (0 to 4,294,967,295) U32 U32 U32
U64 Unsigned Quad Integer (0 to 18,446,744,073,709,551,615)

or roughly (0 to 2e19)

U64 U64 U64
I8 Signed Byte Integer (-128 to 127) I8 I8 I8
I16 Signed Word Integer (-32,768 to 32,767) I16 I16 I16
I32 Signed Long Integer (-2,147,483,648 to 2,147,483,647) I32 I32 I32
I64 Signed Quad Integer (-9,223,372,036,854,775,808 to 9,223,372,036,854,775,807)

or roughly (-1e19 to 1e19)
