Percent (%) symbol is being rendered in italics in the SRS

[BilalM04]

The percent (%) symbol is being rendered in italics in the SRS, when it should not be.

HTML: % is wrapped in an <em></em> tag. For example:

Drasil/code/stable/dblpend/SRS/HTML/DblPend_SRS.html

Line 2374 in 21ff358

<td>10<em>%</em></td>

LaTeX/PDF: % is wrapped in an in-line equation $\%$. For example:

Drasil/code/stable/dblpend/SRS/PDF/DblPend_SRS.tex

Line 1489 in 21ff358

${L_{2}}$ & ${L_{2}}\gt{}0$ & $1.0$ ${\text{m}}$ & 10$\%$

From briefly looking at the Drasil code, it seems that % is defined as an operator, thus it is printed as an expression.

Is % implemented as the modulus operator?

[BilalM04]

Looking at the following code:

Drasil/code/drasil-printers/lib/Language/Drasil/Printing/AST.hs

Lines 9 to 16 in 21ff358

	-- | Different operators.
	data Ops = IsIn | Integer | Real | Rational | Natural | Boolean | Comma | Prime | Log
	| Ln | Sin | Cos | Tan | Sec | Csc | Cot | Arcsin | Arccos | Arctan | Not
	| Dim | Exp | Neg | Cross | Dot | Scale | Eq | NEq | Lt | Gt | LEq | GEq | Impl | Iff
	| Subt | And | Or | Add | Mul | Summ | Inte | Prod | Point | Perc | LArrow | RArrow | ForAll
	| VAdd | VSub | Partial

There doesn't seem to be an explicit modulus operator, just percent (labeled Perc). Thus, I'd assume in Drasil both percent and modulus are implemented together as Perc.

It seems weird to me that Perc is an operator. I would want to trace it some more (i.e. both upstream, as in who generates this Perc and downstream, i.e. how is it actually handled by the printers themselves.)

[balacij]

I would imagine that a % should be rendered in the same slice of code we use to render units -- @BilalM04 do you think that is possible? Do we think this is sensible?
