scaling fixed point numbers

Hai,

For my FIR design i am using 16-bit signed integer coefficients  from
FDAtool instead of fixed point representation

i.e, I am scaling the values as

 0.05937194824218753891 * 65536 =3891..

whether the above scaling will alter the magnitude and phase response
i.e.,cutoff frequency,passband and stopband attenuation setted

regards,
raj
