LaTeX - How to limit the number of characters in a calculated Textfield with hyperref package
I am creating a simple form where people should enter their height and weight with auto-calculation of the corresponding BMI. For this use, I use the option "calculate" from TextField in the hyperref package.
The calculation goes well, but the answer provided gives a number with all decimals (eg. 22.491349480...) and I would like only the first decimal to appear (-> 24.4), and (if possible) the best output beeing a rounded number for the first decimal (->24.5).
The "maxlen=4" command works only when I click inside the field, but the printout is still with all the decimals.
I also tried to change the width of the field, which effectively cuts the answer, but it is impossible to fix a precise width that would show all the different possible lengths.
Would anyone have an idea on how to do this ?
Here is my code :
documentclass[a4paper, 12pt]{article}
usepackage{hyperref}
begin{document}
begin{Form}
noindent
TextField[name=hight,align=0]{Hight [cm]}
\
TextField[name=weight,align=0]{Weight [kg]}
\
noindent
TextField[name=BMI, maxlen=4,align=0,readonly=true,
calculate={%
var f_hight = this.getField("hight");
var f_weight = this.getField("weight");
event.value = f_weight.value /((f_hight.value/100)*
(f_hight.value/100));
}]{BMI}
end{Form}
end{document}

Most likely, you have to restrict the number output within the JavaScript code of the field

shouldn't it be "height" (not related to underlying question)

Definitively should be. I mistranslated from my original code, which is not in english. Thanks !
