Subtract()
OutputVar := instance.Subtract(value)
Subtracts MfUInt64 value from current instance of MfUInt64.
value
The value to subtract from the current instance.
Can be any type that matches IsNumber, var integer or var string of integer numbers.
If ReturnAsObject is true then returns current instance of MfUInt64 with an updated value; Otherwise returns var.
Throws MfNotSupportedException if Readonly is true.
Throws MfNullReferenceException if called as a static method
Throws MfArgumentNullException if value is null.
Throws MfArgumentException if value is not an instance of MfUInt64 and can not be converted into integer value.
Throws MfArgumentOutOfRangeException if adding value is less then MinValue and greater than MaxValue
When subtracting value greater then MfInt64.MaxValue the values must be enclosed in "" and passed as a string as shown in the last part of the example below.
AutoHotkey has an integer upper limit of MfInt64.MaxValue. As a precaution all integer values passed into MfUInt64 methods can be wrapped in double quotes. eg: i := new MfUInt64("10", true)
If value is a float or MfFloat instance then method will alway round down for positive number and round up for negative numbers. For instance 2.8 is converted to 2 and -2.8 is converted to -2.
i := new MfUInt64(MfUInt64.MaxValue, true) ; create new MfInt64 max value and set it RetrunAsObject to value to true
i.Subtract(2) ; i.Value is now 18446744073709551613
iNew := new MfUInt64(5)
MsgBox % i.Subtract(iNew).Value ; displays 18446744073709551608
MsgBox % i.Subtract(10).Value ; displays 18446744073709551598
MsgBox % i.Subtract(3).Subtract("18446744073709451613").Value ; displays 99982
