`bitcastF32()`

Function in Builtins

Reinterpret the bit pattern of a u32 as an f32, the inverse of bitcastU32.

import { bitcastF32 } from 'typeshade'

The signature, the description and the examples come from the compiler's own source at commit 26de7be8.

Syntax

const bitcastF32: (v: ReadonlyNode<"u32">) => Node<"f32">

Parameters

v ReadonlyNode<'u32'>

Return value

Node<'f32'>

Description

Emitted as bitcast<f32>(x) on WGSL and uintBitsToFloat(x) on GLSL. An f32 to u32 to f32 round-trip is a fast-math optimization barrier, since the integer domain is not subject to float reassociation or contraction; optBarrier packages that.

Targets

Target	Support	Notes
WGSL (WebGPU)	Supported	`bitcast<f32>(v)`.
GLSL ES 3.00 (WebGL2)	Supported	`uintBitsToFloat(v)`.
CPU oracle	Supported	Evaluated in f64 by the oracle.
