FractionalPart Function
From GeoGebra Manual
This page is about a feature that is supported only in GeoGebra 4.2. |
- fractionalPart( <Expression> )
- Returns the fractional part of the expression.
Example:
fractionalPart( 6 / 5 )
yields \frac{1}{5},fractionalPart( 1/5 + 3/2 + 2 )
yields \frac{7}{10}.
Note:
In Mathematics fractional part function is defined sometimes as
- x-\lfloor x\rfloor
In other cases as
- sgn(x)(\mid x\mid-\lfloor \mid x\mid\rfloor) .
GeoGebra uses the second definition (also used by Mathematica).
To obtain the first function you may use f(x)=x-floor(x)
