Can any one explain what the (*8) and (*1.1) do in this line

#define DEFAULT_AXIS_STEPS_PER_UNIT {78.7402,78.7402,1520.0*8/3,515*1.1} // default steps per unit for Ultimaker

and isn't it say the first # of 78.7402 the motor steps for x to go 1 mm?

Axis X,Y,Z,E. yes it is the micro steps(1/16) to move 1mm. The *8 and *1.1 are multipliers. It is just as well to use whole numbers in place of the equation. 1520*8/3 =4053.3333

Thank you so much. I kind of figured that but thought it would be better to ask

Does the fractional portion of the number do anything, or does it just get rounded to the nearest whole value? I don't understand how it could perform a fraction of a step, but maybe I'm missing something. Thanks for any help!
