## math.MaxInt32 Constant

The MaxInt32 constant is an inbuilt constant of the math package which is used to get the highest (maximum) value that can be represented by an int32.

The value of math.MaxInt32 constants is 1<<31 - 1 or 2147483647.

Syntax:

```int math.MaxInt32
```

Parameter(s):

• None

Return Value:

The return type of math.MaxInt32 constant is int, it returns the highest (maximum) value that can be represented by an int32.

Example 1:

```// Golang program to demonstrate the
// example of math.MaxInt32 Constant

package main

import (
"fmt"
"math"
)

func main() {
fmt.Printf("Type of math.MaxInt32 is %T\n", math.MaxInt32)
fmt.Println("Value of math.MaxInt32:", math.MaxInt32)
}
```

Output:

```Type of math.MaxInt32 is int
Value of math.MaxInt32: 2147483647
```

Explanation:

In the above program, we imported the math package to use the math.MaxInt32 constant, then printed the type and value of the math.MaxInt32 constant.

Example 2:

```// Golang program to demonstrate the
// example of math.MaxInt32 Constant

package main

import (
"fmt"
"math"
)

// creating function to
// return the value of MaxInt32.
func getMaxInt32() int {
return math.MaxInt32
}

func main() {
fmt.Println("Value of math.MaxInt32:", getMaxInt32())
}
```

Output:

```Value of math.MaxInt32: 2147483647
```
