Public bug reported:
I noticed that gawk floating number calculator function (mpfr_atan2)
prints wrong numbers after 15th decimal.
The following gawk command prints pi:
`awk 'BEGIN { x = 1; y = 1; result = 4*atan2 (y,x); printf " %.20f
degrees\n", result}'`
`3.14159265358979311600 degrees`
But it must be `3.14159265358979323846`
