`toF64()`

Function in Builtins

Widen f32 to f64, exactly (the result is the pair (x, 0.0)).

import { toF64 } from 'typeshade'

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

Syntax

const toF64: (x: ReadonlyNode<"f32"> | number) => Node<"f64">

Parameters

x ReadonlyNode<'f32'> | number

Return value

Node<'f64'>

Description

Widen f32 to f64, exactly (the result is the pair (x, 0.0)). This is the explicit form of the widening the arithmetic methods apply on their own when an f32 meets an f64.
