[comp.text] A TeX question

medhi@uwvax.UUCP (02/24/87)

TeX provides the greater than or equal to symbol ( $\ge$ ) to
print : 
	   >
	   -

I would like to print the following symbol too :

	  >
	  =
      
( to distinguish between non-negative and semi-positive ). 

Could some one out there let me know  how I can produce the  second
symbol ? 

Thanks in advance.

I can't answer your question directly, because I don't have a TeX manual
with me now, but I do have definitions that create the symbols:

Greater or Approximately and Lesser or Approximately.
All you have to do (I think) is to replace the code (218) for "~"
with the appropriate one for "=". However, since "~" may be already raised,
you might have to play also with the numbers (2pt and 3pt).

def\lta{\mathrel{\spose{\lower 3pt\hbox{$\mathchar"218$}}
 \raise 2.0pt\hbox{$\mathchar"13C$}}}
\def\gta{\mathrel{\spose{\lower 3pt\hbox{$\mathchar"218$}}
 \raise 2.0pt\hbox{$\mathchar"13E$}}}

Good luck!
