real math print: printf Xcas cmd 3/4 → ¾ - compsystems - 02-13-2019 03:16 PM
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]

Another example
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";
