Initialization: |
Context('Fraction-NoDecimals');
$answer = Compute('3/2');
|
Setup:
The macro Context("Fraction");
Context("Fraction-NoDecimals");
Context("LimitedFraction");
Context("LimitedProperFraction");
For the differences among these, see the POD documentation contextFraction.pl |
BEGIN_PGML
Simplify [` \displaystyle \frac{6}{4} `].
