f32()

Syntax

function f32(v: number): Node<'f32'>;
function f32(x: ReadonlyNode<ScalarCastSource>): Node<'f32'>;

Parameters

v number

Return value

Node<'f32'>

Exceptions

TypeError

v is neither a JS number nor a scalar node.

SD0116

SD0116 when the node operand is not a scalar.

Description

Most bare-number operands lift to f32 on their own (x.add(1) emits + 1.0 for an f32 x), so this is needed only where a standalone f32 value is wanted outside an operand position: a module-level const, a default argument.

A Node argument is a cast instead, the spelling WGSL and the "use typeshade" surface both write: f32(i) converts, and is the free-function twin of i.f32(). It builds what toF32 builds, so the two spellings share one emit. The operand is bounded to a scalar, which closes a hole both surfaces had: f32(someVec3) type-checked and emitted f32(v), which no target compiles.

Examples

import { f32 } from 'typeshade'

const half = f32(0.5)  // Node<'f32'>
