log()
Function in Builtins
log(x): natural logarithm, component-wise.
import { log } from 'typeshade'
The signature, the description and the examples come from the compiler's own source at commit 26de7be8.
Syntax
const log: <K extends FloatKey>(x: ReadonlyNode<K>) => Node<K>Parameters
xReadonlyNode<K>
Return value
Node<K>
Description
log2 is the base-2 form. x <= 0 is
undefined per spec, so floor the argument with max when it can reach zero.
Examples
Example
import { fn, log, max, f32, f32T } from 'typeshade'
const decayRate = fn('decayRate', { x: f32T }, ({ x }) => log(max(x, f32(1e-6))))Targets
