{{function|fractionalPart}}
;fractionalPart( <Expression> ) :Returns the fractional part of the expression.
{{examples| 1=<div>
*<code><nowiki>fractionalPart( 6 / 5 )</nowiki></code> yields <math>\frac{1}{5}</math> in ''CAS View'', 0.2 in ''Algebra View''
*<code><nowiki>fractionalPart( 1/5 + 3/2 + 2 )</nowiki></code> yields <math>\frac{7}{10}</math> in ''CAS View'', 0.7 in ''Algebra View''
</div>}}
{{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>
