This tutorial will help us in converting the string into an integer. In Haskell, the process of converting a string to an integer typically involves using the read function or readMaybe function from the Text.Read module. Another approach is to use the digitToInt function from the Data.Char module to convert each character in the string to its corresponding numerical value. All these functions are part of the standard library and we can use them to easily convert strings to integers in Haskell. Algorithm Step 1 − in-build() function is defined using read function. Step 2 − Program execution will ... Read More

This tutorial will help us in finding the arctangent of the given value. The arctangent is the inverse function of the tangent. The tangent of an angle is defined as the ratio of the length of the side opposite the angle to the length of the side adjacent to the angle in a right triangle. The arctangent, therefore, gives the measure of an angle (in radians) whose tangent is a given value. Syntax atan(angle) Here, atan() is a built-in function and value is passed as parameter to compute the arctangent of the value passed. The arctangent is a periodic ... Read More

This tutorial will help us in finding arccosine of the given value. The arccosine is the inverse function of the cosine. If given a value between -1 and 1, it returns the angle (in radians) whose cosine is equal to that value. For example, the cosine of pi/3 radians is equal to 0.5. Therefore, if you pass 0.5 as an input to the arccosine function, it should return pi/3 radians. Syntax acos(angle) Here, acos() is a built-in function and value is passed as parameter to compute the arccosine of the value passed. Method 1: Finding arccosine using in-built ... Read More

This tutorial will help us in finding the arcsine of the given value. The arcsine is the inverse function of the sine. It takes the output value of the sine function, and returns the input angle that would produce that output value. The arcsine function is useful in trigonometry and geometry in finding missing angles and sides in right-angled triangles. Syntax asin(angle) Here, asin() is a built-in function and value is passed as parameter to compute the arcsine of the value passed. The arcsine function maps a value between -1 and 1 to an angle between -π/2 and π/2 ... Read More

This tutorial will help us in finding hyperbolic tangent of the given radian value. The hyperbolic functions are used to calculate the angles and the distances. The hyperbolic tangent function gives us the hyperbolic tangent value of the radian angle. The angle value must be a radian value. If the angle is any degree value then, it must be converted into radian value first. Syntax tanh(angle) ... Read More

This tutorial will help us in calculating the volume of a cube. The volume of a cube is a measure of the amount of space inside the cube. It is calculated by multiplying the length of one side of the cube (s) by itself three times. The formula to calculate the volume of a cube is − V = s^3 Where V is the volume and s is the length of one side of the cube. In other words, it's the cube of the side length. Method 1: Using volumeOfCube Function In this method, the function volumeOfCube is defined ... Read More

This tutorial will help us in calculating the area of a cube. There are various approaches to calculating the area but the mathematical formula to calculate the area will remain the same I.e., 6*(side^2). Method 1: Using cubeArea Function This example defines a function cubeArea that takes a single argument, the length of the cube's sides, and returns the area of the cube. The main function calls the cubeArea function to calculate the area. The result is then printed to the console. Algorithm Step 1 − The function cubeArea is being defined on the basis of simple mathematical formula ... Read More

This tutorial will help us in calculating the sum of all odd numbers up to N. Haskell uses a functional programming paradigm, which means that it uses functions to transform data, rather than using loops and variables to keep track of state changes. There are different ways to calculate the sum of all odd numbers u to N in Haskell. Method 1: Using List Comprehension In this method, the function sumOddNumbers uses a list comprehension to generate a list of all odd numbers up to n, and then uses the sum function to calculate the sum of the numbers in ...

This tutorial will help us in calculating the sum of all even numbers. Haskell uses a functional programming paradigm, which means that it uses functions to transform data, rather than using loops and variables to keep track of state changes. There are different ways to calculate the sum of all even numbers between 1 and 100 in Haskell. Algorithm Step 1 − Program execution will be started from main function. The main() function has whole control of the program. It is written as main = do. Step 2 − The list comprehension [x | x

This tutorial will help us in checking whether a variable is defined or not. In Haskell, a variable is considered defined if it has a value assigned to it. The value can be of any type, including a special type called Maybe that is used to represent values that may or may not be present. Algorithm Step 1 − The Data.Maybe module is imported. Step 2 − The checkDefined function is defined as, checkDefined x = isJust x. It takes a Maybe value and returns a Bool indicating whether the value is Just (i.e. defined) or Nothing (i.e. not ...
