Hello,

I've checked this with a Bsource both two syntaxes work fine

b3 n001 0 v=(pow(-1,round((- 2 *((1)-1)/2+1)/- 1)))

b1 n002 0 v=(-1)**round((- 2 *(1 -1)/2+1)/- 1)

With a bsource using a function directive only one works

b3 n001 V=ch2(zz) neither V=ch3(zz) wrong

b3 n001 V=ch4(zz) good

.param a=2 b=1 zz=1

.func ch2(x)=(-1)**round((-a*(x-1)/2+1)/(-1)/b); ==> errorlog
(-1)**round((- 2 *(( 1 )-1)/2+1)/(-1)/ 1 芦))禄

.func ch3(x)=(-1)**round((-a*(x-1)/2+1)/-b) ; ==> errorlog
(-1)**round((- 2 *(( 1 )-1)/2+1)/- 1 芦))禄

.func ch4(x)=pow(-1,round((-a*(x-1)/2+1)/-b)) ; ==> good



I'am sure that two syntaxes were correct before because almost all
the files in the below section provide errors

Hello Didier

The reason for that is because of the syntax for .func, it should be by the book:
.func f(x) {...}
not f(x)=...

There may also be some outdated symbols/libraries. I'll make the changes and update the files with the correct syntax later (but possibly much later).

Thanks a lot Vlad.
You抳e done a very good job
I抳e download your last update Your examples work now
