real math print: printf Xcas cmd 3/4 → ¾

[compsystems]

Hello
Xcas has a function to print in prettyprint (2D) very important to show equations and results as in textbooks, please hpprime develop group incorporate this function

PHP Code:

function area_of_the_triangle()
begin 

                local Base, Height, Answer;

                assume(Base,float);

                assume(Height,float);

                assume(Answer,float);


                DispG; ClrGraph; ClrIO;


                printf( "Please enter the base of the triangle" );

                input( Base );


                printf( "Please enter the height of the triangle" );

                input( Height );


                Answer := 1 / 2 * (Base * Height);

                printf( "The area of the triangle is %gen ", Answer )
                print( "The area of the triangle is ", Answer )

                printf( x^2 );  // x²
                print( x^2 ); // x^2

                return Done;

ffunction; 


area_of_the_triangle() [enter] then 1/2 then 3 returns in pretty print
"The area of the triangle is ¾"

with print cmd ( print lineary) returns

"The area of the triangle is 3/4"


[enter]

PHP Code:

testPrintformat():={
  local f,Slope, Roots, Area, x, pos（a）, pos﹝b﹞;
  
  assume(x,symbol);
  
  DispG, ClrIO;
  f(x):=-2*x^2-4*x+12;
  printf("f(x):%gen",f(x));
  
  Slope:=unapply(diff(f(x),x),x);
  printf("Slope:∂xfx)=%gen",right(Slope));
  
  pos（a）:=-4;  print(pos（a）);
  pos﹝b﹞:=-1;  print(pos﹝b﹞);

  print(Slope(pos（a）));  
  print(Slope(pos﹝b﹞)) 

    
  Roots:=solve(f(x)=0,x);
  printf("Roots:%gen ~ %gen", Roots, approx(Roots)); 
  
  Area:=int(f(x),x,Roots(1),Roots(2));
  printf("Area:%gen ~ %gen", Area, approx(Area)); 
  return "Done";
