In the documentation to the "Export" function it says that 

"Machine-precision numbers are by default written to six-digit precision".

If I try:

z = {{Pi, 2 Pi}, {10, 100.}} // N
{{3.14159, 6.28319}, {10., 100.}}

Export["z1.dat", z]

I get the file "z1.dat":

3.141592653589793   6.283185307179586
10.                 100.

This is not 6-digit precision. Is there a way to specify the precision that the
"Export" function should  use?
