[JASS] Getting a fraction from a decimal

[Element of Water]

Ok, so i want a Fraction object, simply because I find it easier to work in fractions than decimals personally. I want a method to work out a fraction from a decimal. How would I do this? (I know it's possible because my calculator can do it)

library Fraction
    struct Fraction
        integer num
        integer den
        real value
        
        static method create takes integer num, integer den returns Fraction
            local Fraction f = Fractionn.allocate()
            
            set f.num = num
            set f.den = den
            set f.value = I2R(num)/I2R(den)
            
            return f
        endmethod
        
        static method createFromReal takes real value returns Fraction
            local Fraction f = Fraction.allocate()
            
            set f.value = value
            //what here???
            
            return f
        endmethod
    endstruct
endlibrary

What I should do is setting num = value*100 and den = 100.
And then trying to simplify(don't know good english word) the fraction. Maybe dividing num and den by numbers that give modulus 0 on both numbers. You could do that with a loop that checks all prime numbers from 2 till half of current den.

Simplify is the exact term my maths teacher uses in england

Thanks. I know how to simplify logically. I'll give it a go.
