## math.MaxInt64 Constant

The MinInt64 constant is an inbuilt constant of the math package which is used to get the lowest (minimum) value that can be represented by an int64.

The value of math.MinInt64 constants is -1 << 63 or -9223372036854775808.

Syntax:

```int math.MinInt64
```

Parameter(s):

• None

Return Value:

The return type of math.MinInt64 constant is int, it returns the lowest (minimum) value that can be represented by an int64.

Example 1:

```// Golang program to demonstrate the
// example of math.MinInt64 Constant

package main

import (
"fmt"
"math"
)

func main() {
fmt.Printf("Type of math.MinInt64 is %T\n", math.MinInt64)
fmt.Println("Value of math.MinInt64:", math.MinInt64)
}
```

Output:

```Type of math.MinInt64 is int
Value of math.MinInt64: -9223372036854775808
```

Explanation:

In the above program, we imported the math package to use the math.MinInt64 constant, then printed the type and value of the math.MinInt64 constant.

Example 2:

```// Golang program to demonstrate the
// example of math.MinInt64 Constant

package main

import (
"fmt"
"math"
)

// creating function to
// return the value of MinInt64.
func getMinInt64() int {
return math.MinInt64
}

func main() {
fmt.Println("Value of math.MinInt64:", getMinInt64())
}
```

Output:

```Type of math.MinInt64 is int
Value of math.MinInt64: -9223372036854775808
```
