The law of variable proportion states that as we employ more and more units of a variable input, keeping other inputs fixed, the total product initially increases at an increasing rate then increases at a declining rate, and finally starts falling.

Followed by the name of our variable, pi: var pi float64. And finally the data type float64: var pi float64. We can optionally specify an initial value as well, such as 3.14: var pi float64 = 3.14. Go is a statically typed language. Statically typed means that each statement in the program is checked at compile time.
