I made a calculator in swift ui but the function I made for division works, but it doesn't work correctly, for example to make 25/2= 12.5 mine makes 25/2=12.0 so I round the result I put the function here Below if anyone can help me and write me the correct function, thank you very much in advance everyone :)
func calculate() {
let expression = NSExpression(format: displayText)
if let result = expression.expressionValue(with: nil, context: nil) as? Decimal {
let fullOperation = "\(displayText) = \(result)"
displayText = "\(result)"
history.append(fullOperation)
} else {
displayText = "Error"
}
}

} //fine divisione
