Haskell Program to Convert Boolean to String
In Haskell, we can convert Boolean to String by using user-defined function along with guards and if-else statements. In the first example, we are going to use (boolToString True = "True" and boolToString False = "False") function and in the second example, we are going to use (boolToString b | b = "True" | otherwise = "False") as function definition. And in the third example, we are going to use (boolToString b = if b then "True" else "False"). Algorithm Step 1 − Define the Boolean function Step 2 − Program execution will be started from main function. ...

In Haskell, we can use functions like foldl, recursion, and list comprehension to convert a binary number to decimal. In the first example, we are going to use (binToDec = foldl (\acc x -> 2*acc + digitToInt x) 0) and in the second example, we are going to use base case, (binToDec "" = 0) and recursive case, (binToDec (x:xs) = 2 * binToDec xs + digitToInt x) function. And in the third example, we are going to use (binToDec = sum . zipWith (\x y -> 2^x * digitToInt y) [0..] . reverse). Algorithm Step 1 − ...
Read MoreHaskell Program to convert Decimal to Binary
In Haskell, we will convert Decimal to Binary by using reverse function , tail recursion, and divMod function. In the first example, we are going to use (decToBin n | n < 0 = error "Input must be non-negative" | n == 0 = "0" | otherwise = reverse $ decToBin' n) and in the second example, we are going to use (binDigits 0 = "" and binDigits n = let (q, r) = n `divMod` 2 in show r ++ binDigits q) function. Method 1: Using reverse function and tail recursion In ...
Read MoreHaskell Program to convert Decimal to Hexadecimal
In Haskell, we can use intToDigits, showIntAtBase and format functions to convert a decimal to Hexadecimal number. In the first example, we are going to use (decToHex n = reverse (hexChars n) where hexChars 0 = "" and hexChars x = intToDigit (x `mod` 16) : hexChars (x `div` 16)) and in the second example, we are going to use (decToHex n = showIntAtBase 16 intToDigit n "") function. In the third example, we are going to use (decToHex n = printf "%X" n) function. Method 1: Using reverse and intToDigits functions In this method, the Data.Char module is ...
Read MoreHaskell Program to get the predecessor of an integer number using library function
In Haskell, we can use library function like pred, subtraction and fromMaybe to get the predecessor of an integer number. In the first example, we are going to use (pred number) function and in the second example, we are going to use subtraction while in third example, we are going to use (fromMaybe 0 (predMaybe x)) function. 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. It calls the pred function with the value and prints its predecessor ...
Read MoreHaskell Program to get the Division and Remainder using library function
In Haskell, we can use divMod and quotRem functions to get the division and remainder of a given number. In the first example, we are going to use (divMod x y) function and in the second example, we are going to use (quotRem 20 7) function. 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 variables named, “x” and “y” are being initialized. The interal function will divide them by taking them as argument. Step ...
Read MoreHaskell Program to get the real part from a Complex number
In Haskell, we can use realPart function and pattern matching to get the real part from a complex number. In the first example we are going to use (realPart c) function and in the second example, we are going to use patter matching as (x:+_) = c. Algorithm Step 1 − The Data.Complex module is imported to work over the complex numbers. Step 2 − Program execution will be started from main function. The main() function has whole control of the program. It is written as main = do. Step 3 − The variable named, “c” is being ...
Read MoreHaskell Program to check a given number is finite or not
In Haskell, we can use isIEEE, isInfinite and isNaN functions to check whether a given number is finite or not. In the first example we are going to use (isIEEE n) function with if-else statement and in the second example, we are going to use (isInfinite n) function. And in third example, we are going to use (isNaN) function along with (isInfinite n) function. 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 variable named, ...
Read MoreHaskell Program to get the numerator from a rational number
In Haskell, we can use numerator, div, quot and gcd functions to find the numerator from a given rational number. In the first example we are going to use numerator (r) function and in the second example, we are going to use (n `div` gcd n d) function. And in third example, we are going to use (numerator r `quot` gcd (numerator r) (denominator r)) function. Algorithm Step 1 − The Data.Ratio module is imported to use numerator function. Step 2 − Program execution will be started from main function. The main() function has whole control of the program. ...
Read MorePandas series Vs. single-column DataFrame
Introduction This article compares and contrasts Python's Pandas library's single-column DataFrames and Pandas Series data structures. The goal of the paper is to clearly explain the two data structures, their similarities and differences. To assist readers in selecting the best alternative for their particular use case, it contains comparisons between the two structures and practical examples on aspects like data type, indexing, slicing, and performance. The essay is appropriate for Python programmers at the basic and intermediate levels who are already familiar with Pandas and wish to get a deeper grasp of these two key data structures. What is Pandas? ...
