ubit

To Binary String

Inspired by biu.

Convert integer to binary string.

fmt.Println(ubit.ToBinaryString(4))               // [00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000100]
fmt.Println(ubit.ToBinaryString(int8(5)))         // 00000101
fmt.Println(ubit.ToBinaryString(int16(9)))        // [00000000 00001001]
fmt.Println(ubit.ToBinaryString([]byte{1, 2, 3})) // [00000001 00000010 00000011]

f := float32(5.20)
s := ubit.ToBinaryString(f)
fmt.Println("s =", s) // [01000000 10100110 01100110 01100110]

var outf float32
ubit.ReadBinaryString(s, &outf)
fmt.Println("outf =", outf) // 5.2
