While testing the patch I found a minor preexisting (mine...) bug: when
string-scanning doubles, whether the whole string is consumed or not is
not checked. This means that -D x=0one is interpreted as double 0.
I came up with the attached check, but maybe there is a cleaner way to do
I like the way the zic code does it:
+ char xs;
! if (sscanf(var->value, "%lf%c", &dv, &xs) != 1)
Indeed... I cannot say that it is cleaner such, but at least it is short
and it avoids the strlen call.
Neither way allows for trailing whitespace, though. I don't see that
that's important here.
No, this is not an issue here for variables specified from the command
line. Consider pushing this fix?
