Variable-binding operators are logical operators that occur in almost every formal language. A binding operator Q takes two arguments: a variable v and an expression P, and when applied to its arguments produces a new expression Q(v, P). The meaning of binding operators is supplied by the semantics of the language and does not concern us here.
An effective, binding price floor, causing a surplus (supply exceeds demand) By contrast, in the second graph, the dashed green line represents a price floor set above the free-market price. In this case, the price floor has a measurable impact on the market. It ensures prices stay high, causing a surplus in the market.
Tacit programming, also called point-free style, is a programming paradigm in which function definitions do not identify the arguments (or "points") on which they operate. Instead the definitions merely compose other functions, among which are combinators that manipulate the arguments.
Another example is a paper by Sen et al. that found that gasoline prices were higher in states that instituted price ceilings. [18] Another example is the Supreme Court of Pakistan decision regarding fixing a ceiling price for sugar at 45 Pakistani rupees per kilogram. Sugar disappeared from the market because of a cartel of sugar producers and ...
For example, Python bindings are used when an extant C library, written for some purpose, is to be used from Python. Another example is libsvn which is written in C to provide an API to access the Subversion software repository. To access Subversion from within Java code, libsvnjavahl can be used, which depends on libsvn being installed and ...
For example, in the snippet of Python code on the right, two functions are defined: square and sum_of_squares. square computes the square of a number; sum_of_squares computes the sum of all squares up to a number. (For example, square(4) is 4 2 = 16, and sum_of_squares(4) is 0 2 + 1 2 + 2 2 + 3 2 + 4 2 = 30.)
