sorting numbers with sort -n

Looking for help for sort, I learned that for sorting numbers I use: sort -n but it seems that that is not enough when you have numbers like 0.2000E+7 for example, sort -n will not worry about the E+7 part, and will just sort the numbers like 0.2000. Exapmle: cat example.txt .91000E+07...

rwbytype.d

rwbytype.d(1m)							   USER COMMANDS						    rwbytype.d(1m)

NAME

       rwbytype.d - read/write bytes by vnode type. Uses DTrace.

SYNOPSIS

       rwbytype.d

DESCRIPTION

       This program identifies the vnode type of read/write activity - whether that is for regular files, sockets, character special devices, etc.
       This is measuring at the application level, so file activity may well be cached by the system.

       Since this uses DTrace, only users with root privileges can run this command.

EXAMPLES

       This samples until Ctrl-C is hit.
	      # rwbytype.d

FIELDS

       PID    process ID

       CMD    process name

       VNODE  vnode type (describes I/O type)

       DIR    direction, Read or Write

       BYTES  total bytes

DOCUMENTATION

       See the DTraceToolkit for further documentation under the Docs directory. The DTraceToolkit docs may include full worked examples with ver-
       bose descriptions explaining the output.

EXIT

       rwbytype.d will sample until Ctrl-C is hit.
