Subtract()
OutputVar := instance.Subtract(value)
Subtracts value from current instance of MfBigInt.
value
The value to subtract from the current instance.
Can be var integer representation or any type that matches IsIntegerNumber or MfUInt64 or MfBigInt
If ReturnAsObject is true then returns current instance of MfBigInt with an updated value; Otherwise returns var containing integer.
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 MfBigInt and can not be converted into integer value.
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 MfBigInt("908908898903445454544", true) ; create new MfBigInt and set it RetrunAsObject to value to true
i.Subtract(2) ; i.Value is now 908908898903445454542
iNew := new MfInt64(5545487787)
MsgBox % i.Subtract(iNew).Value ; displays 908908898903445454542
MsgBox % i.Subtract("59345340583534").Value ; displays 908908839558104871008
MsgBox % i.Subtract(389789897).Subtract("89890853453453453453453").Value ; displays -88981944613895738372342
