How to Get Uint64 Type Random Number in Golang?
Go language provides inbuilt support for generating random numbers of the specified type with the help of a math/rand package. This package implements pseudo-random number generators. These random numbers are generated by a source and this source produces a deterministic sequence of values whenever the program run. And if you want to random numbers for security-sensitive work, then use the crypto/rand package.
You are allowed to generate a pseudo-random number of 64-bit integer as an uint64 type from the default source with the help of the Uint64() function provided by the math/rand package. So, you need to add a math/rand package in your program with the help of the import keyword to access the Uint64() function.
func Uint64() uint64
Let us discuss this concept with the help of the given examples:
Random Number 1: 5577006791947779410 Random Number 2: 8674665223082153551 Random Number 3: 15352856648520921629
Result 1: 5577006791947779423 Result 2: 8674665223082153654 Result 3: 15352856648520921809
