The result of the following commands:

> formatC(9.9, 1, format="fg")
[1] "1e+01"
> formatC(99.9, 1, format="fg")
[1] "1e+02"

does not seem to be coherent with what the help page says:

>  format: equal to `"d"'  (for integers), `"f"', `"e"', `"E"', `"g"',

I would expect "fg" to produce only fixed format numbers, which does not
seem to be the case here.
