import (

    "log"
    "math"
    "strings"

    "github.com/stevenferrer/gread"
)

func main() {

        math.MaxInt32,
        math.MaxInt64,
        math.MaxUint32,
        uint64(math.MaxUint64),
        math.MaxFloat32,
        math.MaxFloat64,
    )
    
    // Create a new `gread.Reader`
    reader := gread.NewReader(strings.NewReader(s))
    
    i32, err := reader.NextInt32()
    checkErr(err)
    fmt.Printf("%T is %d\n\n", i32, i32)

    i64, err := reader.NextInt64()
