Floor() if the largest integer not greater than its argument. Round()
is the nearest integer to its argument.
The ternary(x,y,z) function is the equivalent of the ternary operator
(? and :) in C or C++. It takes 3 arguments. The first argument is a
conditional. The result of the function is y if x evaluates to true
(non-zero). The result is z if x evaluates to false (zero).
The ramp(x,y) function uses the current timestep to generate a value
linearly interpolated between the specified x,y values over the course
of a run, according to this formula:
