How to remove trailing zeros from a string in Swift

Answer 1

import Foundation

func removeTrailingZeros(_ str: String) -> String {
    var result = str
    
    while result.hasSuffix("0") {
        result = String(result.dropLast())
    }

    if result.hasSuffix(".") {
        result = String(result.dropLast())
    }

    return result
}

var str = "457833.8591000"

str = removeTrailingZeros(str)

print(str)



/*
run:
 
457833.8591
 
*/
