Integer Min Max Ranges

Name	Type	Range
uint8	unsigned 8-bit integer	(0 to 255)
uint16	unsigned 16-bit integer	(0 to 65535)
uint32	unsigned 32-bit integer	(0 to 4294967295)
uint64	unsigned 64-bit integer	(0 to 18446744073709551615)
int8	signed 8-bit integer	(-128 to 127)
int16	signed 16-bit integer	(-32768 to 32767)
int32	signed 32-bit integer	(-2147483648 to 2147483647)
int64	signed 64-bit integer	(-9223372036854775808 to 9223372036854775807)

Here is a golang example showing how to find the minimum and maximum values of a int32 using a brute force approach:

Source: (example.go)

package main
 
import "fmt"
 
func main() {
 
   max := int32(0)
   for i := int32(0); i>=0; i++ {
      max = i
   }
   fmt.Println("Max:", max)
 
   min := int32(0)
   for i := int32(0); i<=0; i-- {
      min = i
   }
   fmt.Println("Min:", min)
}
 

Output:

$ go run example.go
Max: 2147483647
Min: -2147483648
