c# - Format doubles with General numeric format and pad right with zeros -

-

i'm trying output doubles of various sizes, negative , non-negative, columns. use g5 standard numerical format exponential format when appropriate (i.e. values tiny), regular formatting otherwise. values padded zeros appropriately line in columns (i.e. pad zeros on right normally, , pad zeros before e in exponentials). currently, have:

string.format("{0}  {1}  {2}", a.tostring("g5"), b.tostring("g5"), c.tostring("g5"));

this doesn't work great since doesn't pad. output this:

 1.234000000  0.123400000  1.23450e-03  4.56780e-08  -1.2345e-09  0.001234000  // negative signs can line else -12.34500000  0.045678900 -1.23450e-06  // or line each other, whatever easier, not both

how can achieve this?

edit: using : format {0:10} above numbers yields:

1.234  0.1234  0.0012345 4.5678e-08  -1.2345e-09  0.001234 -12.345  0.045679  -1.2345e-06
