{{Note|1=<br>
In Mathematics fractional part function is defined sometimes as<br> 
:<math>x-\lfloor x\rfloor </math><br>
In other cases as<br>
:<math>sgn(x)(\mid x\mid-\lfloor \mid x\mid\rfloor) </math>. <br>
'''''GeoGebra''''' uses the second definition (also used by Mathematica).<br>
To obtain the first function you may use '''<code>f(x) = x - floor(x)</code>'''<br>
