Get two digits after point for float

Question

I have a float value as float s = 1.270001 . I need to get two digits as output ie 1.27 . But when we use %0.02f it gives output as 1.28

How to get two digits after decimal point ex: 1.16 as 1.16 only

`1.89  as 1.89` only but not `1.90`

Answer 1

You can do it by using NumberFormatter

let formatter = NumberFormatter()
formatter.locale = Locale.current
formatter.numberStyle = .decimal
formatter.maximumFractionDigits = 2
formatter.roundingMode = .floor
let stringValue = formatter.string(from:1.270001)!
print(stringValue)

Output:

1.27
