This haskell tutorial will help us in calculating the value from the given fraction and exponent of a number. To find this, the input is taken as fraction and exponent, and its corresponding value is computed. Algorithm Step 1 − The “Data.Ratio” is imported to work over fractions. Step 2 − The calculateValue function is defined Step 3 − Program execution will be started from main function. The main() function has whole control of the program. It is written as main = do. Step 4 − The variables named, “fraction” and “exponent” are initialized. ... Read More
