mod

Function

Returns the floor-modulo remainder of x divided by y, with the sign of y, componentwise over vectors.

The signature and the sentence under each name are the compiler's own text at commit 26de7be8.

Syntax

declare function mod(a0: number, a1: number): number
declare function mod<T extends Numeric>(a0: T, a1: T): T

A number in a parameter or a return position is the scalar slot. The ambient file declares a GPU scalar as a branded number whose brand is optional, so a literal and any branded scalar both fill it.

type f32 = number & { readonly [f32Tag]?: true }

A declaration you write still needs a width, and a bare number on a field or a parameter is refused; the TypeScript constructs page carries that row with the compiler's own message.

A signature may name a type the ambient file declares for its own use. These are those declarations.

Numeric
type Numeric = number | vec2 | vec3 | vec4 | vec2i | vec3i | vec4i | vec2u | vec3u | vec4u

Parameters

A parameter named by position (a0, a1) carries a name the ambient file generates. A call passes its arguments in order and names none of them.

  • a0 numberT
  • a1 numberT

Return value

numberT

Description

mod(-7, 3) returns 2, not -1 like the % operator, which uses truncating modulo.

Targets

WGSL
(a - b * floor(a / b))
GLSL ES 3.00
mod(a, b)
