Int

Integers default to 64 bit signed numbers.

let x = 42

Other integer sizes supported are described below. To declare a variable with a specific integer size, append the size suffix to the value.

F# Equivalent	Description	Suffix	Examples
int8	signed 8 bit number	y	let fizz = 42y
uint8	unsigned 8 bit number	uy	let buzz = 42uy
int16	signed 16 bit number	s	let fizz = 42s
uint16	unsigned 16 bit number	us	let buzz = 42us
int32	signed 32 bit number	l	let fizz = 42l
uint32	unsigned 32 bit number	ul	let buzz = 42ul
int64	signed 64 bit number (default)	L	let fizz = 42 (no suffix)
uint64	unsigned 64 bit number	uL	let buzz = 42uL
int128	signed 128 bit number	Q	let fizz = 42Q
uint128	unsigned 128 bit number	Z	let buzz = 42Z

Functions

Absolute Value

The mathmatical absolute value of the integer.

Definition

Int.absoluteValue(Int: a) -> Int

Example

let x = -1
let y = 1
let X = Int.absoluteValue x
let Y = Int.absoluteValue y
[X,Y]

This trace returns: [1,1]

---

Add

The sum of two integers.

Definition

Int.add(Int: a, Int: b) -> Int

Example

let x = -1
let y = 1
let z = Int.add x y
z

This trace returns: 0

---

Clamp

Constrains a value to a range. If the value is within the range defined by the parameters the input value is returned. If the value is outside the range, the range boundary closest to the input value is returned.

Definition

Int.clamp(Int: value, Int: limitA, Int: limitB) -> Int

Parameter	Definition
value	The input value to check against the range bounds.
limitA	One end of the range.
limitB	The other end of the range.

Examples

let value = 5
let lowerBound = 1
let upperBound = 9
Int.clamp value lowerBound upperBound

This trace returns: 5

let value = 10
let lowerBound = 1
let upperBound = 9
Int.clamp value upperBound lowerBound

This trace returns: 9
