`max()`

Function in Builtins

max(a, b): component-wise maximum, the partner of min(/api/min/).

import { max } from 'typeshade'

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

Syntax

const max: <K extends FloatKey | Float64Key | IntKey>(
  a: ReadonlyNode<K>,
  b: NoInfer<ArithArg<K>>,
) => Node<K>

Parameters

a ReadonlyNode<K>
b NoInfer<ArithArg<K>>

Return value

Node<K>

Description

b may be a scalar broadcast against a vector a. A common floor idiom is max(x, f32(1e-6)), which keeps a divisor or a sqrt or log argument off zero without a branch.

Examples

Example

import { fn, max, f32, f32T } from 'typeshade'

const safe = fn('safe', { x: f32T }, ({ x }) => max(x, f32(1e-6)))

Targets

Target	Support	Notes
WGSL (WebGPU)	Supported	`max(a, b)`. Over `f64` operands the fp64 pass rewrites it into its `df64` helper.
GLSL ES 3.00 (WebGL2)	Supported	`max(a, b)`. Over `f64` operands the fp64 pass rewrites it into its `df64` helper.
CPU oracle	Supported	Evaluated in f64 by the oracle.
