What is the Law of Variable Proportions? The Law of Variable Proportion s states that as the quantity of a factor is increased while keeping other factors constant, the Total Product (TP) first rises at an incremental rate, then at a decremental rate and lastly the total production begins to fall.

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.
