Coercing to character

[asanquer@virbac.fr]

Hi,

I've got a problem when I coerce a numeric value to a character: I loose
some decimal digits after the decimal point.

Example:

> x <- c(3.45,3.40)
> as.character(x)
[1] "3.45" "3.4"

I really want to keep the 2 decimal digits. Does someone can give me a
tip-off?

I had also noted that when I export some data frame to an ASCII file, I
loose the null decimal digit (with numeric data). An explanation and may be
a solution?

Thank a lot,
