<Operators in Golang

Okay, I’m new to Go lang, but this doesn’t make sense to me:

package main

 import (
     "fmt"
     "log"
 )

 var rectLen, rectWidth float64 = 0, 0

 func init() {
     fmt.Println("init is initialized")
     if rectLen <0 {
         log.Fatal("rectLen smaller than 0")
     }
     if rectWidth <0 {
         log.Fatal("rectWidht smaller than 0")
     }
 }

 func main() {
     fmt.Println("Main is initialized")
     fmt.Println(rectLen, rectWidth)
 }
 

This will print:

init is initialized
 Main is initialized
 0 0
 

Why are 0 and 0 printed when my init function “protects” my rectLen and rectWidth variable should be strictly greater than 0? If I change the value to something less than 0 it works fine and I get:

init is initialized
 2009/11/10 23:00:00 rectLen smaller than 0
 

Thank you!

Because < is different from “equal to” .Try changing the operator to <=. This will only be triggered if your value is less than OR equal to 0
