There is no float type. Looks like you want float64. You could also use float32 if you only need a single-precision floating point value. package main import "fmt" func main() { i := 5 f := float64(i) fmt.Printf("f is %f\n", f) }…

[Q7] 把数倒过来 Given a 32-bit signed integer, reverse digits of an integer. Example 1: Input: 123 Output: 321 Example 2: Input: -123 Output: -321 Example 3: Input: 120 Output: 21 Solution: https://leetcode.com/problems/reverse-integer/discuss/229800/Pyt…
function isFloat(n) { return n === +n && n !== (n|0); } function isInteger(n) { // 仅能检查32位的数字 return n === +n && n === (n|0); } 要点: n === +n用于检测是否numeric n|0用于round 由于OP操作符(即|),目前仅支持32位,故超过32位的数字无法通过isInteger检测 灵感来源…
