FOR LOOPS – Double Numbers

var sampleArray = [8.0, 7.0, 19.0, 28.0]

for (index,value) in sampleArray.enumerated(){

    sampleArray [index] = value / 2

}

print(sampleArray)

// ".0" in each number changes it from integer to double, that way when we divide them by 2  the result will be more accurate.


Another way to do it: 

var sampleArray = [Double]()
sampleArray = [8.0, 7.0, 19.0, 28.0]
for (index,value) in sampleArray.enumerated(){
sampleArray [index] = value / 2

}

print(sampleArray)

Happy coding ;)
