Description
Can somebody please clarify where in the VVC spec the logic implemented by this VTM function is described ?
int convertMvFloatToFixed(int val)
{
int exponent = val & MV_EXPONENT_MASK;
int mantissa = val >> MV_EXPONENT_BITCOUNT;
return exponent == 0 ? mantissa : (mantissa ^ MV_MANTISSA_LIMIT) << (exponent - 1);
}

See 8.5.2.15 Temporal motion buffer compression process for collocated motion vectors. Note that it combines convertMvFixedToFloat and convertMvFloatToFixed.
