arithmetic, by paying attention to summation order or reorganization of
mathematical expressions. The default configuration uses mixed
precision, but it is easy to turn on double precision by adding the
-option ``-DGMX\_DOUBLE=on`` to ``cmake``. Double precision will be 20 to 100%
+option ``-DGMX_DOUBLE=on`` to ``cmake``. Double precision will be 20 to 100%
slower than mixed precision depending on the architecture you are
running on. Double precision will use somewhat more memory and run
input, energy and full-precision trajectory files will be almost twice
