Wonderful 
Thank you Tomaaz, your Turtle library is very useful to produce amazing turtle graphics / arts.
Thank you also to Marcus for giving us an insight regarding numbers in n7.

Herewith another turtle experiment :
   

First experiment : turtle library contained int()           
     produced "shifted green lines"

Second experiment : turtle library without int()  
     produced clean blue lines

Code:

'-------------------------------------------------------------
' Modified turtle library
'  First Experiment : function forward (dlugosc) with int()
'  Second Experiment :function forward3(dlugosc) without int()
'-------------------------------------------------------------

include "turtle_modified.n7"

set window "Turtle Experiment",640,360
reset() 'set angle to 0
set color 0,0,0;cls 'clear screen
iteration = 100

'FIRST experiment
set color 0,255,0 'green
goxy(300,120)
for i = 1 to iteration
    forward(50)
    turnleft(45)
next

'SECOND experiment
set color 0,0,255 'blue
goxy(350,120)
for i = 1 to iteration
    forward3(50)
    turnleft(45)
