cordic sincos output usage

Hi all,



I m using cordic ip core in spartan 6 device,futher im getting the 
correct outputs too, but facing problem in multiplying tat output to 
some number( like pwm ontime).



For Example



Input: Pin(phase): 0001100100011110



Output: cos(theta):Xout: 0010110101000111



Output: Sin(theta):Yout: 0010110100111011





from above example,



Phase in = 45 degrees or 0.785 in radians in 2QN format.



Xout: 11591 in decimal format, 0.7071067 in 1QN format

Yout : 11579 in decimal format, 0.7071 in 1QN format



Now consider ,

I want to multiply 50 * Xout



     = 50 * 11591  is what im able to do,but actually i need to do this 
= 50 * 0.7071067





Please can any one help me out!!!!





Thanks in Advance
