MathML and fractions

[jmtrik]

The are a few ways you can generate typeset maths. Below are a number of options that you can try when generating expressions. They behave slightly differently to each other but I include them here for discussion.

$a1=maple("x^(5/2)");

#temporarily assign to variable inside maple call
$d1=maple("a1:=$a1:printf(MathML[ExportPresentation](a1))");

#whole calculation done in maple call
$d2=maple("a1:=x^(5/2):printf(MathML[ExportPresentation](a1))");

# using codegen
$a3=maple("x^(5/2)");
$d3=maple("codegen[MathML]($a1)");

#using just Export
$a4=maple("x^(5/2)");
$d4=maple("printf(MathML[Export]($a1))");

# if you prefer the 5/2 form
$a5=maple("x^(5/2)");
$d5=maple("printf(MathML[ExportPresentation]($a1))");

Here is the output they generate. Notice that $d1 to $d4 give the same result, but $d5 is different. Under the hood the first 4 are generating fractions using the MathML <mfrac> whereas $d5 is using <mrow>.
