Not just the military world. On the the biggest consumers of CPU
cycles around here is a program which calculates rna secondary structures
by an energy minimization process. All in integer math, using as the base
unit 0.1Kcal. Virtually the only floating point in the program is a
floating divide by 10.0 at the end to print the result in a form more
familiar to human readers.
