响应式 Math 方法
用法
ts

const base = ref(2)
const exponent = ref(3)
const result = useMath('pow', base, exponent) // Ref<8>
const num = ref(2)
const root = useMath('sqrt', num) // Ref<1.4142135623730951>
num.value = 4
console.log(root.value) // 2类型声明
typescript
export type UseMathKeys = keyof {
[K in keyof Math as Math[K] extends (...args: any) => any
? K
: never]: unknown
}
