Tomasz Sowa 939d0f7519 fixed: Big::Mod(x) didn't correctly return a carry ...

and the result was sometimes very big (even greater than x)
fixed:   global function Mod(x) didn't set an ErrorCode object
fixed:   global function Round() didn't test a carry
         now it sets ErrorCode object
changed: function Sin(x) to Sin(x, ErrorCode * err=0)
         when x was very big the function returns zero
         now it sets ErrorCode object to err_overflow
         and the result is undefined
         the same is to Cos() function
changed: PrepareSin(x) is using Big::Mod() now when reducing 2PI period
         should be a little accurate especially on a very big 'x'
