Re: [NTG-context] Use \unit for value and uncertainty

[Otared Kavian]

Hi Benjamin,

Thanks for sharing your nice code, which is very useful.
However I wanted to let you know that it seems it does not work correctly with 
LuaMetaTeX version 2020.04.30 11:10, even though it works fine with ConTeXt 
mkiv.

Best regards: Otared K.

Re: [NTG-context] Use \unit for value and uncertainty

[Benjamin Buchmuller]

I know this is quite an old thread, but here is a minimal parser (\units with 
an “s”) that wraps around \digits and \unit to produce an acceptable output. 

As I frequently need to write ranges (or measures of uncertainty), I find it 
convenient to able to type

\units{4.0 to 5.0 centi meter} 

than 

\digits{4.0}\,to\,\unit{5.0 centi meter}.

Also, the parser will take care of exponents and bracket them accordingly. :D

ranges: keyword “to”: 4.0 – 5.0 cm
SEM:keyword “se”: 4.5 ± 0.5 cm
SD: keyword “sd”: 4.5 (0.5) cm

If no keyword is present, the default behaviour is \unit{…}.

The code is not perfect (and the level of abstraction potentially not yet 
sufficient to make it part of the phys-dim.mkiv source), but maybe helpful.

\starttext

\startluacode
userdata = userdata or {}

function userdata.units(input)

tbl = string.explode(input)

if tbl[2] == "to" then
context.digits(tbl[1])
context.phys_units_space()
context("--")
context.phys_units_space()
context.unit(table.concat(tbl, " ", 3))
elseif tbl[2] == "se" then
local sx1 = string.split(tbl[1], "e")
local sx2 = string.split(tbl[3], "e")
if (sx1[2] == sx2[2]) and not (sx1[2] == nil) then
context("(")
context.digits(sx1[1])
context.phys_units_space()
context("±")
context.phys_units_space()
context.digits(sx2[1])
context(")")
context.digits("e" .. sx1[2])
context.phys_units_space()
context.unit(table.concat(tbl, " ", 4))
else
context.digits(tbl[1])
context.phys_units_space()
context("±")
context.phys_units_space()
context.unit(table.concat(tbl, " ", 3))
end
elseif tbl[2] == "sd" then
local sx1 = string.split(tbl[1], "e")
local sx2 = string.split(tbl[3], "e")
if (sx1[2] == sx2[2]) and not (sx1[2] == nil) then
context.digits(sx1[1])
context.phys_units_space()
context("(")
context.digits(sx2[1])
context(")")
context.digits("e" .. sx1[2])
context.phys_units_space()
context.unit(table.concat(tbl, " ", 4))
else
context.digits(tbl[1])
context.phys_units_space()
context("(")
context.digits(tbl[3])
context(")")
context.unit(table.concat(tbl, " ", 4))
end
else
context.unit(table.concat(tbl, " "))
end

end
\stopluacode

\def\units#1{\ctxlua{userdata.units("#1")}}

Car 1 drives \units{4 to 5.2 kilo meter per hour}.

Car 2 drives \units{30.1 to 40.5 kilo meter per hour}.

Car 3 drives \units{40.= to 50.= kilo meter per hour}.

The average speed was \units{35,000 se 5000 meter per hour}.

The average speed was \units{35e3 se 0.5e3 meter per hour}.

The average speed was \units{35.2e3 se 5e2 meter per hour}.

\stoptext

The average speed was \units{35.2 se 5e2 meter per hour}.

The average speed was \units{_3.2 sd 5 meter per hour}.

Re: [NTG-context] Use \unit for value and uncertainty

[Florian Leupold]

Hello!

There does not seem to be a simple solution to using \unit with uncertainties, 
see below.

Could someone maybe point me to the relevant source code for the parser for 
\unit in MKIV? Then I would try to modify/improve the code myself.

Thanks a lot and best regards,
Florian

[NTG-context] Use \unit for value and uncertainty

[Florian Leupold]

Dear list

Is it possible to use the units module (in MKIV) for value plusminus 
uncertainty in a way similar to the \SI command in LaTeX, like
  \unit{(1.59\pm2)e-19 coulomb} or
  \unit{1.59(2)e-19 coulomb}?

Thanks and best regards,
Florian
