Holger Vogt 1605d293d0 Add function integ to control language 
Trapezoidal rule for integrating a vector.

Holger Vogt bb9f1669f6 Enable math characters also in tokens like i(z/z) by 
temporarily putting " around the token.

Improve error message on missing vector

Holger Vogt e93a19e3e8 Allow math characters in node names 
Add a function ft_getpnames_quotes()
It puts quotes " around tokens xxx, when these are enclosed as
V(xxx) and contain arithmetic characters. V(R*C) becomes
V("R*C"). After settig up the parse tree, the quotes are removed again.
Thus these math character remain part of the node name and are not
parsed as parts of an equation.

Holger Vogt 4a3b193154 remove memory leak in function parser (bug. no 478), 
second case
 2020-04-04 14:13:01 +02:00
Holger Vogt 11cf6e709b third trial: get the token i(vss) as a whole in the lexer, 
this prevents the parser from generating the spurious vector vss.
No need to do an extra translation i(vss) -> vss#branch.

Jim Monte 068df274bf Made ft_numparse() thread-safe (no internal static variables) and prepared to support ngspice variable type CP_NUM. 2020-03-15 08:50:52 +01:00
Holger Vogt b9901a2569 [PATCH 47] Refactored ft_getnames() and used the new function in 
com_let().

Holger Vogt f33c3f0751 remove memory leak, when ft_getnames ... free_pnode couple 
parses a vector like v(1,2)
 2018-10-13 18:18:23 +02:00
Holger Vogt 2dd293707b initialize pn in ft_getpnames() parse.c 
initialize dwLen in tesCreateSystemInfo() in com_sysinfo.c
Both were reported by MSVC Code Analysis
Crash of ngspice.dll in Eeschema is thus removed
(hopefully in general)

rlar c6a8429258 src/maths/cmaths, implement `nint()' (.control language) 2014-09-20 17:15:10 +02:00
rlar 2602a492b2 fix `log' in `B' and in `.control', to base e instead of 10 
In the B language this can be considered a bug fix.

In the .control language this is a severe change
  and breaks backwards compatibility.

In all three languages 'numparam' 'B' and '.control' we now have
  ln    to the base e
  log   to the base e
  log10 to the base 10

Thus log and log10 is now consistent
  with the vast majority of programming languages.

ln is merely for convenience.
  very few other languages have it.
  I'd like to discourage its usage.
