looking at the documentation I think you need to start with an
NSDecimalNumber then use one of the member functions to convert it to an
NSDecimal, do the things you want to do on it, and convert it back again.
Remember also that NSDecimal is really just a structure, not an object,
so when you declare it you'd normally do it on the stack, not as a pointer.
so I think I'd try something like
NSDecimal decinum = [ [ NSDecimalNumber decimalNumberWithMantissa:1675
exponent:-2 isNegative:NO ] decimalValue ];
I suppose you could try to make one directly by doing
NSDecimal myDec;
then setting myDec._exponent and myDec._mantissa[], if you can figure
out how it stores its mantissa but that seems to be more work and they
are private so you'd be opening yourself up to apple changing the whole
thing later.

Hi folks,
Can someone tell me how I create an NSDecimal? The C struct one, not the ObjC
NSDecimalNumber. For performance and simplicity I'd rather use the C interface
but for the life of me I can't find out how to actually create one of these and
assign a value to it.
\\Declare
NSDecimal *decimal;
\\assign<file:///\\assign>? Surely its not as simple as this?
decimal = 16.75
