NSDecimalNumber Integer Fix

So given the decimal 109268.27107118553088 the result is:

32-bit architecture

integer: 0
int: 109268
uint: 109268
unsigned integer: 0

64-bit architecture

integer: -75199
int: 109268
uint: 109268
unsigned integer: 109268

Solution

extension NSDecimalNumber {
    
    override public var integerValue: Int {
        return Int(doubleValue)
    }
    
    override public var unsignedIntegerValue: UInt {
        return UInt(doubleValue)
    }
}

Result

integer: 109268
int: 109268
uint: 109268
unsigned integer: 109268
