For a scale factor 0, we are done. Good work, thank you!
A scale factor != 0 does not work yet, you wrote you are still working on it,
is that correct?

I am now. ;)


print "(-2pg12.3)", 0.02 ! 0.200E-01 expected 0.002E+01
print "(-1pg12.3)", 0.02 ! 0.200E-01 expected 0.020E+00
print "(0pg12.3)", 0.02 ! 0.200E-01
print "(1pg12.3)", 0.02 ! 0.200E-01 expected 2.000E-02
print "(2pg12.3)", 0.02 ! 0.200E-01 expected 20.00E-03

My confusion seems to be when scale factor is to be ignored and when not, I will give the standard another read.
