bad presentation of \sum

[retsyo]

when the result of

s = r"\sum_{i=1}^{10}\frac{ \large \sigma_{zp,i}}{E_i} kN"

convert_to_mathml(s)

is copied into MS Word, we can find that there is an extra dotted-line block after the \sum symbol

is it a bug?

[retsyo]

my bad, it should be

r"\sum_{i=1}^{10}{\frac{\sigma_{zp,i}}{E_i} kN"

[retsyo]

sorry to re-open should \sum_{i=1}^{10}\frac{\sigma_{zp,i}} {E_i} kN mean

now it is

[retsyo]

the same thing happens on

\int_{1}^{5}x\mathrm{d}x
\prod_{j=1}^{3} y_{j}
\lim\limits_{x \to 0} \frac{a^x}{b+c}

Closing this for now as I cannot see any difference between latex2mathml output and MathJax.

I wrote a separate ticket in https://github.com/roniemartinez/latex2mathml/issues/301

[retsyo]

the problem can be solved easily: use {} to embrace every item, for example, we do not use

\int_{1}^{5}x\mathrm{d}x   

\prod_{j=1}^{3} y_{j}   

\lim\limits_{x \to 0} \frac{a^x}{b+c}  

but use

\int_{1}^{5}{x}\mathrm{d}x
\prod_{j=1}^{3} {y_{j}}
\lim\limits_{x \to 0} {\frac{a^x}{b+c}}
