The go math/big package provides an implementation of arbitrary-precision arithmetic on non-negative integers, rational numbers, and floating-point numbers. The bit.IntSign function is a method of the big.Int type used to report the sign of an arbitrary-precision integer.

Code Examples:

1. Determining the sign of a big integer

package main

import (

"fmt"

"math/big"

)

func main() {

x := big.NewInt(-5)

sign := x.Sign()

fmt.Println(sign) // Output: -1

}

In this example, we create a new big.Int instance with the value -5 and call the Sign() method to determine its sign. Since the value of x is negative, Sign() returns -1.

2. Comparing the signs of two big integers

package main

import (

"fmt"

"math/big"

)

func main() {

x := big.NewInt(7)

y := big.NewInt(-9)

xSign := x.Sign()

ySign := y.Sign()

if xSign == ySign {

fmt.Println("Both integers have the same sign.")

} else {

fmt.Println("The integers have different signs.")

}

}

In this example, we create two big integers x and y with values of 7 and -9, respectively. We then call the Sign() method on each integer to determine their signs and compare the results. Since x is positive and y is negative, xSign and ySign will be different, and we'll print "The integers have different signs.".

The package library for these examples is "math/big".
