It seems that there is now one leading space or a leading _ if negative. JVERSION Installer: j602a_win.exe Engine: j602/2008-03-03/16:45 Library: 6.02.049

The 'bug fix' Roger made for 6.01 means that now the code does not conform to the Dictionary, which says (for ":): Otherwise (if w<0 or d<0), the result is put in exponential form (with one digit before the decimal point) and is left-justified except for two fixed spaces on the left (including one for a possible negative sign). The two fixed spaces have been removed. 1. There is no way to request exponential formatting with no fractional digits. In previous releases __ ": 10 would format to 1e1, but in 6.02 it is a domain error. (__j.0) doesn't work either. Can this be put back the way it used to work (and documented in DoJ)? Otherwise there is no way to format exponentials with no fraction. I am going leave printf unchanged until this is resolved.
