Basic types

In this article

This topic lists the basic types that are defined in F#. These types are the most fundamental in F#, forming the basis of nearly every F# program. They are a superset of .NET primitive types.

Type .NET type Description Example bool Boolean Possible values are true and false. true/false uint8, byte Byte Values from 0 to 255. 1uy int8, sbyte SByte Values from -128 to 127. 1y int16 Int16 Values from -32768 to 32767. 1s uint16 UInt16 Values from 0 to 65535. 1us int32, int Int32 Values from -2,147,483,648 to 2,147,483,647. 1 uint32, uint UInt32 Values from 0 to 4,294,967,295. 1u int64 Int64 Values from -9,223,372,036,854,775,808 to 9,223,372,036,854,775,807. 1L uint64 UInt64 Values from 0 to 18,446,744,073,709,551,615. 1UL nativeint IntPtr A native pointer as a signed integer. nativeint 1 unativeint UIntPtr A native pointer as an unsigned integer. unativeint 1 decimal Decimal A floating point data type that has at least 28 significant digits. 1.0m float, double Double A 64-bit floating point type. 1.0 float32, single Single A 32-bit floating point type. 1.0f char Char Unicode character values. 'c' string String Unicode text. "str" unit not applicable Indicates the absence of an actual value. The type has only one formal value, which is denoted (). The unit value, (), is often used as a placeholder where a value is needed but no real value is available or makes sense. ()

Note

You can perform computations with integers too big for the 64-bit integer type by using the bigint type. bigint is not considered a basic type; it is an abbreviation for System.Numerics.BigInteger.
