`floor()`

Function in Builtins

floor(x): round toward −∞, component-wise.

import { floor } from 'typeshade'

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

Syntax

const floor: <K extends FloatKey | Float64Key>(
  x: ReadonlyNode<K>,
) => Node<K>

Node<K>

ceil, trunc and round are the other rounding directions, and fract computes x.sub(floor(x)) in one call.

import { fn, floor, f32T } from 'typeshade'

const cell = fn('cell', { x: f32T }, ({ x }) => floor(x))

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