Why 100/1000 is not 0.10 in swift palyground?

Question

I am facing a problem where I am not getting values of decimal places here is the code that I used to run in Swift Playground

print(100/1000)
print(Float(100/1000))

Expected Output :

0.10
0.10

Actual Output:

0
0.0

You're doing integer divisions, you're getting integer result — Cid, Sep 11 '20 at 12:45
Think: `print(100/1000); print(Float(100/1000)); print(Float(100)/1000); print(100/Float(1000)); print(Float(100)/Float(1000))`. 5 "possibilities". Integer can't have decimal, right? If so, Float(someInteger), where `someInteger` is `100/1000`, and you got before 0, that's normal to have 0.0, because that's `Float(0)`, no? — Larme, Sep 11 '20 at 12:46

Because of this:

let variable = 100/1000
print(type(of: variable))
// prints Int

@VarunNaharia because `100/1000`, the integer division equals 0. `Float(0)` equals `0.0` – Cid Sep 11 '20 at 12:48
100/1000 = 0, so Float(0) = 0.0 – Roman Ryzhiy Sep 11 '20 at 12:49

Just do the following:

print(100.0 / 1000.0)
print(Float(100) / Float(1000))

So in order to get a floating point result you need to divide floating point numbers instead of two integers
