Shouldn't that difficult - create a class

For the mantissa, use an array - you can put 15 significant digits per element


UPDATE

14 significant digits per element

add a sign field

add methods for Add() and Sub()



If it's only for integers you're done, if not you'll have to add a field for the exponent and a method to normalize
