printing of complex numbers in R-alpha
Hello everyone
I am finding complex numbers to be printed oddly in R-alpha.
> 1e100+1e100i
[1] 1e+100+1e+100i
> 1e100 + 1e44i
[1] 1e+100+100000000000000008821361405306422640701865984i
> dput(1e100+1e44i)
1e+100+100000000000000008821361405306422640701865984i

The first line is what I would expect, the second and third lines
aren't:
I would prefer "1e100+1e44i"...
