Natural fractions. How can I enter a value to display the integer and fractional part, like 2½. Maybe somewhere there is a full-fledged Help?

... Maybe like this

Greetings!

I understand your question, but such a feature isn't built into SMath. However, there are ways to mitigate this lack of support.

If you wish for special characters (e.g., ｢½｣) to be treated as a number, you can declare then as such:
  
      There are a few of these fraction characters you can define as a variable:
            


If you wish to type a fraction in as you propose (2½ ), this isn't so easy. You can use a matrix and then add the values together (i.e., Σ[2 ½]). This reads kinda like a fraction, but is needlessly bulky:
  


If the goal is to have the result of 2.5 itself to report as 2½ instead of 5/2; there isn't much you can do. The one thing you can do is create a function that will convert your number and report that fraction as type "string"


Hope this helps!

"dec2frac(decimal)" Works for me! Thank you! I've been using a sheet from MathCad, which is not as clear:

Even the Oscar's solution is very elegant, this is another approach, based on the Nasch work.

As an application, using a vernier (the English version here, but without the students comments)

Best regards.
