I won't be asking for a source code yet. What I need to figure out is the process of a certain Math problem with the equation that seemed to be impossible to be converted to source code.

Here it goes:

**A certain waveform is 0 volts for time less than 2 seconds and 3 volts for time equal to or greater than 2 seconds. (These waveforms are referred to as step functions.) Prompt the user accepts time in the variable named time and displays the appropriate voltage, depending on the input value.**

So the problem is asking for a program for voltage/seconds relation. The user inputs any duration (in seconds) and it is supposed to display the appropriate voltage.

This problem, I guess, is an example of step/greatest integer function, having the equation y= **n<=x** or where n is the greatest integer less than or greater than x. Step function also follows the equation y=[[x]].

So if a user inputs 5 seconds, it should display 6 volts. If a user inputs 9 seconds, it should display 12 volts.

So...how do I convert the equation to a proper process for source code?
