#randx - Random Utilities

#Overview

The randx module provides high-performance random number generation with cryptographically secure random support.

#Functions

#Int()

Generate random integer.

func Int() int

Returns:

• Random integer

Example:

num := randx.Int()

#Intn()

Generate random integer in range [0, n).

func Intn(n int) int

Parameters:

• n - Maximum value (exclusive)

Returns:

• Random integer in [0, n)

Example:

num := randx.Intn(10)  // 0-9

#IntnRange()

Generate random integer in range [min, max].

func IntnRange(min, max int) int

Parameters:

• min - Minimum value (inclusive)
• max - Maximum value (inclusive)

Returns:

• Random integer in [min, max]

Example:

num := randx.IntnRange(1, 10)  // 1-10

#Int64()

Generate random int64.

func Int64() int64

Returns:

• Random int64

Example:

num := randx.Int64()

#Float64()

Generate random float64.

func Float64() float64

Returns:

• Random float64 in [0.0, 1.0)

Example: go num := randx.Float64()

---

### Float64Range()

Generate random float64 in range [min, max].

```go
func Float64Range(min, max float64) float64

Parameters:

• min - Minimum value
• max - Maximum value

Returns:

• Random float64 in [min, max]

Example:

num := randx.Float64Range(0.0, 100.0)

#Bool()

Generate random boolean.

func Bool() bool

Returns:

• Random boolean

Example:

flag := randx.Bool()

#Usage Patterns

#Random Numbers

// Random age
age := randx.IntnRange(18, 65)

// Random price
price := randx.Float64Range(10.0, 1000.0)

// Random quantity
quantity := randx.IntnRange(1, 100)

#Random Selection

items := []string{"apple", "banana", "cherry", "date", "elderberry"}
index := randx.Intn(len(items))
selected := items[index]

#Random Data

type User struct {
    ID       int64
    Name     string
    Age      int
    Active   bool
    Price    float64
}

user := User{
    ID:     randx.Int64(),
    Name:    "User",
    Age:     randx.IntnRange(18, 65),
    Active:  randx.Bool(),
    Price:   randx.Float64Range(0.0, 1000.0),
}
