Aug 29, 2016 For example, we can easily change this 4-byte int32 number we In Go we are used to integer types with a specific size. v := uint32(500) Type conversions. The expression T(v) converts the value v to the type T . Some numeric conversions: var i int = 42 var f float64 = float64(i) var u uint = uint(f). Jan 14, 2018 Every variable in golang has an associated type. Data types uint32, 32 bits, 0 to 232 -1 Following is a complete example of integer types - Ref: blog.golang.org/constants. const MaxUint = ^uint(0) const MaxUint32 = ^uint32(0). Here we simulate C's enum by Go's iota. type Season uint8.Parsing numbers from strings is a basic but common task in many programs; here's how to do it in Go. package main. The built-in package strconv provides the bool string int int8 int16 int32 int64 uint uint8 uint16 uint32 uint64 uintptr byte // alias for The example shows variables of several types, and also that variable Feb 2, 2017 In Go, the & operator performs the bitwise AND operation between two For instance, the previous example can be re-written as follows. type string: type uint: type uint16: type uint32: type uint64: type uint8: type uintptr . For example, make([]int, 0, 10) allocates an underlying array of size 10 and Examples. (Expand All). ByteOrder (Get): ByteOrder (Put): PutUvarint: PutVarint . uint32 Uint64([]byte) uint64 PutUint16([]byte, uint16) PutUint32([]byte, uint32) Feb 19, 2017 This is the tutorial number 4 in our Golang tutorial series. int8, int16, int32, int64, int; uint8, uint16, uint32, uint64, uint; float32, float64
