i32()

Syntax

function i32(v: number): Node<'i32'>;
function i32(x: ReadonlyNode<ScalarCastSource>): Node<'i32'>;

Parameters

v number

Return value

Node<'i32'>

Exceptions

TypeError

v is neither a JS number nor a scalar node.

SD0116

SD0116 when the node operand is not a scalar.

Description

Use it over the f32 default wherever a value must type-check as a signed integer: array and loop indices, matchExpr and matchEnum scrutinees, texture layer arguments.

A Node argument is a cast instead: i32(x) converts, the free-function twin of x.i32(). It builds what toI32 builds, and its operand is bounded to a scalar.

Examples

import { i32 } from 'typeshade'

const zero = i32(0)  // Node<'i32'>
