Is there an equal sign with wider gap?












6















I am trying to make a large unary operator from an equal sign =, namely, mathlarger{boldsymbol{=}}, but the bars are too close together to distinguish from the general binary case. Is there some package with = having a wider gap that I can use?

    I'm not sure what unary equality is supposed to denote but, if you're having trouble distinguishing your symbol for it from ordinary equality, that suggests you might want to look at a completely different symbol.

  • @DavidRicherby thanks for the suggestion, I use unary equal to refer to the set that is the isovalue contour of point p, so it can be intuitive.

Here's a proposal:



documentclass{article}
usepackage{amsmath,xparse}

ExplSyntaxOn
NewDocumentCommand{uneq}{}
{
mathbin{mathpaletteupdraft_uneq:nn {}}
}

dim_new:N l__updraft_width_dim
dim_new:N l__updraft_height_dim

cs_new_protected:Nn updraft_uneq:nn
{
vcenter
{
mathsurround=0pt
hbox:n
{
% measure the width of the equals sign in the current style
hbox_set:Nn l_tmpa_box {$#1{=}$}
dim_set:Nn l__updraft_width_dim { box_wd:N l_tmpa_box }
% measure the width of 1mu in the current style
hbox_set:Nn l_tmpa_box {$#1mkern1mu$}
dim_set:Nn l__updraft_height_dim { box_wd:N l_tmpa_box }
% start drawing
driver_draw_begin:
% round caps on lines
driver_draw_cap_round:
% set the line width (change 1.2 to your liking)
driver_draw_linewidth:n { 1.2l__updraft_height_dim }
% 1. cm fonts use width/10 of side bearings
% 2. the gap between lines is 5 times the line width
% bottom line
driver_draw_moveto:nn
{ 0.1 l__updraft_width_dim }
{ -2.5 l__updraft_height_dim }
driver_draw_lineto:nn
{ 0.9 l__updraft_width_dim }
{ -2.5 l__updraft_height_dim }
driver_draw_stroke:

driver_draw_moveto:nn

driver_draw_lineto:nn

{ 2.5 l__updraft_height_dim }
driver_draw_stroke:
driver_draw_end:
% occupy the space
hspace{ l__updraft_width_dim }
}
}
}
ExplSyntaxOff

begin{document}

$mathbin{=}A$

$uneq A$ $scriptstyleuneq A$ $scriptscriptstyleuneq A$

$A=B$

end{document}


There is no “unary operator” class, one has to use mathbin and TeX will act according to the context. You could also decide to simply use mathord.

The gap can be tweaked by changing the 4LMpt.



documentclass{article}
usepackage{scalerel,stackengine,bm}
newcommandbineq{mathbin{ThisStyle{ensurestackMath{vcenter{hbox{stackengine{%
