Today I learned that Latex supports many different typefaces: https://www.overleaf.com/learn/latex/font_typefaces and http://www.personal.ceu.hu/tex/typeface.htm
I’ve seen papers like this one (https://arxiv.org/pdf/2006.15704.pdf) uses a different font for subroutines (like function names or APIs). One example is from their reference to the “CrossEntropyLoss” function:
Now, I try by myself different typefaces and see which one it uses:
{\rm CrossEntropyLoss rm}
{\sl CrossEntropyLoss sl}
{\sf CrossEntropyLoss sf}
{\sf CrossEntropyLoss sf}
{\tt CrossEntropyLoss tt}
{\sc CrossEntropyLoss sc}
{\fontfamily{qcr}\selectfont
CrossEntropyLoss qcr
}
{\fontfamily{bch}\selectfont
CrossEntropyLoss bch
}
{\fontfamily{lmtt}\selectfont
CrossEntropyLoss lmtt
}
I think the closest font is lmtt
.
