Golang Program to get the magnitude of the given number
In this article we will discuss about how to get the magnitude of a number in Go language. Magnitude of a quantity is defined as its numeric value. Magnitude of a number is always positive. In this article we will discuss about different methods by which we can obtain the magnitude of any number. Syntax func Abs(number float64) float64 Abs() is a method defined in math library. This method accepts a 64 bit float number as an argument and return the absolute value of it excluding the sign. The source code to the above stated problem is compiled and ...
Read MoreGolang Program to Display Prime Numbers Between Two Intervals using library functions.
In this article we will discuss about how to display prime numbers between two intervals using functions in Go language. Syntax func Sieve(n int) []int func IsPrime(n int) bool If else conditionals in GO language: If condition { // code to be executed } else { // code to be executed } For loop as a while loop in GO language: for condition { // code to be executed // increment or decrement the count variable. } Sieve() function defined in primes package accepts ...
Read MoreGolang Program to create Complex numbers from given imaginary parts using In-build Library Function
In this tutorial we will learn how to create Complex numbers from given imaginary parts in Go programming language. A complex number is a basic data type of GoLang and is a combination of the real and imaginary part, where both parts of the complex number will be float type in golang. Complex Number = Real Number + Imaginary Number The function complex()in Go programming language is a built-in function that is used to construct a complex number from two floating-point values. The real and imaginary parts of the complex value must be of the same size and the return ...
Read MoreGolang Program to convert string type variables into Boolean
In this tutorial, we will learn how to f convert string type variables into Boolean in Go programming language. Boolean Vs String Boolean is a data type having 1-byte size. It can store any one of the three values mainly True, False or none. It acts like a flag to show whether a condition is correct or not. String data type is used to store a sequence of characters. it can be in the form of literals or alphabets. The size of string variable is 1 byte or 8 bits. For this task various types of string conversions are needed, ...
Read MoreGolang Program to convert Decimal to Octal
In this article you will know how to convert the decimal number to octal in Go language. For this we are going to use the FormatInt() function of strconv package. When we say convert the decimal number to octal, it means to convert the number with the base value 10 to the base value 8. The base value means the number of digits required to represent the numeric value. Example 1: Go Language Program to convert Decimal Number to Octal using Library Function Syntax func FormatInt(input int64, base int) string for [condition | ( init; condition; increment) | Range] ...
Read MoreGolang Program to convert Decimal to Hexadecimal
In this article you will learn the go language code to convert decimal number to Hexadecimal. Decimal Number Vs Hexadecimal Numbers Decimal numbers are the numbers which have base 10, which means each digit of a number can have an integer value ranging from 0 to 9 (10 possibilities) depending on its position. For example, 23 is a decimal number. Any number contains 16 digits in it, it is based on base 16, which means hexadecimal numbers contains decimal number from 0 to 9 and extra 6 Alphabets. A−F. In go language all the hexadecimal numbers start with 0x or ...

Read MoreGolang Program to Check if An Array Contains a Given Value
In this tutorial we will learn how to check if a given value is present in a Go−lang array or not. We will use 2 methods for this. Method 1: Using a for loop directly in the main function We will use a for loop to iterate over the elements of an array in Golang and check for the equality of values using the equality operator. If the values match then we can stop the iteration and say that the given value is present in the array. Method 2: Using the function Golang does not have any pre-defined library function ...
Read MoreGolang Program to make a Simple Calculator using Switch Case
In this tutorial we will see how to make a simple calculator using switch case statements in Go programming language. The switch statement will assess an expression, comparing the expression's value against a series of case conditions given in a series and executes the statement after the first condition with a matching value, until a break is encountered. Golang Basic switch case with default A switch statement runs the first case equal to the choice entered. The cases are evaluated in an order and it stops when a case succeeds. If no case (choice entered) matches, it is a ...
Read MoreGolang Program to get total bits required for the given number using library function
In this article we will discuss about how to get total bits required for the given number using library function in Go language. To get the total number of bits of any number we need to represent that number in binary which is a combination of zeroes and ones and then count the number of zeroes and ones. For example: 16 can be converted in binary as 10000 and therefore number of bits in number 16 are 5. 65 can be converted in binary as 1000001 and therefore number of bits in number 65 are 7. Syntax Functions − func ...
