"A single two-input gate suffices for all of Boolean logic in digital hardware. No comparable primitive has been known for continuous
mathematics: computing elementary functions such as sin, cos, sqrt, and
log has always required multiple distinct operations. Here I show that a single binary operator, eml(x,y)=exp(x)-ln(y), together with the
constant 1, generates the standard repertoire of a scientific
calculator. This includes constants such as e, pi, and i; arithmetic operations including addition, subtraction, multiplication, division,
and exponentiation as well as the usual transcendental and algebraic functions."
