formatFix
formats to fixed point number format.
It 'writes' x
with sign (" " or "-"), with before
decimals before the "." and with after
decimals after the ".". If after == 0
then the "." will be omitted.
There will always be at least one decimal digit before the "."
If before
is too small to represent x
: if
extend==TRUE
, the string will be extended, else a string
consisting of "*" of length before+after
will be given.
If abs(x) >= 10^8, values very near 10^k cannot be represented
exactly, so the normal format
will be used.
Names are retained. The vector or array structure will be preserved
