Golang Type Conversions

This is a creation in Article, where the information may have evolved or changed.

Golang is a strongly typed language, which is used in the basic type conversion process. Here's a look at the common type conversions, which are constantly updated.

Shaping A string

Fmt. Println (StrConv. Itoa (100))

The source code for this method is:

Itoa is shorthand for formatint (I, ten). Func Itoa (i int) string {return Formatint (Int64 (i), 10)}

Can be seen is a simple implementation of the Formatint method.

String to reshape

I, _: = StrConv. Atoi ("+") fmt. Println (i)

64-bit shaping of the turn string

var i int64i = 0x100fmt. Println (StrConv. Formatint (i, 10))

Formatint The second parameter represents the binary, and 10 represents the decimal.

BYTE-to-32-bit shaping

B: = []byte{0x00, 0x00, 0x03, 0xe8}bytesbuffer: = bytes. Newbuffer (b) var x int32binary. Read (Bytesbuffer, Binary. Bigendian, &x) fmt. PRINTLN (x)

where binary. The Bigendian represents the byte order, and the corresponding little endian. Popular parlance is called big-endian, small end.

32-bit shaping of the turn byte

var x int32x = 106bytesBuffer: = bytes. Newbuffer ([]byte{}) binary. Write (Bytesbuffer, Binary. Bigendian, X) fmt. Println (Bytesbuffer.bytes ())

byte-to-string

Fmt. Println (String ([]byte{97, 98, 99, 100})

String to Byte

Fmt. Println ([]byte ("ABCD"))
