import "math/big" func main() { x := big.NewFloat(3.14159) // create a new Float value with initial value x.SetPrec(64) // set the precision to 64 bits }
import "math/big" import "fmt" func main() { x := big.NewFloat(2) x.SetPrec(256) // set the precision to 256 bits sqrt := new(big.Float).Sqrt(x) // calculate the square root with higher precision fmt.Println(sqrt) }In this example, we create a new Float value with an initial value of 2 and set its precision to 256 bits. We then use the Sqrt method of the big.Float type to calculate the square root of the value with higher precision. The result is printed using the fmt package. Package library: math/big
