math.Ilogb() Function in Golang With Examples
Go language provides inbuilt support for basic constants and mathematical functions to perform operations on the numbers with the help of the math package. You can find the binary exponent of the specified number as an integer with the help of ILogb() function provided by the math package. So, you need to add a math package in your program with the help of the import keyword to access the ILogb() function.
Syntax:
func Ilogb(a float64) int
- If Ilogb(±Inf), then this function will return MaxInt32.
- If Ilogb(0), then this function will return MinInt32.
- If Ilogb(NaN), then this function will return MaxInt32.
Example 1:
// Golang program to illustrate // the math.Ilogb() function package main import ( "fmt" "math" ) // Main function func main() { // Finding binary exponent of // the given number as an integer // Using Ilogb() function res_1 := math.Ilogb(math.Inf(-1)) res_2 := math.Ilogb(math.Inf(1)) res_3 := math.Ilogb(0) res_4 := math.Ilogb(1) res_5 := math.Ilogb(math.NaN()) // Displaying the result fmt.Printf( "\nResult 1: %d" , res_1) fmt.Printf( "\nResult 2: %d" , res_2) fmt.Printf( "\nResult 3: %d" , res_3) fmt.Printf( "\nResult 4: %d" , res_4) fmt.Printf( "\nResult 5: %d" , res_5) } |
Output:
Result 1: 2147483647 Result 2: 2147483647 Result 3: -2147483648 Result 4: 0 Result 5: 2147483647
Example 2:
// Golang program to illustrate // the math.Ilogb() function package main import ( "fmt" "math" ) // Main function func main() { // Finding binary exponent of // the given number as an integer // Using Ilogb() function nvalue_1 := math.Ilogb(math.Inf(-1)) nvalue_2 := math.Ilogb(math.Inf(1)) // Sum of the given numbers res := nvalue_1 + nvalue_2 fmt.Printf( "%d + %d = %d" , nvalue_1, nvalue_2, res) } |
Output:
2147483647 + 2147483647 = -2
