For example, sometimes instead of rounding off a numerical value obtained from a calculation, some of the digits might just be removed i.e. truncated See also [ edit ]
For example, = = =. The result 1 × 10 − 3 {\displaystyle 1\times 10^{-3}} is clearly representable, but there is not much faith in it. This is closely related to the phenomenon of catastrophic cancellation , in which the two numbers are known to be approximations.
In numerical analysis, the ITP method (Interpolate Truncate and Project method) is the first root-finding algorithm that achieves the superlinear convergence of the secant method [1] while retaining the optimal [2] worst-case performance of the bisection method. [3]
Another example, encoding an alphabet of size 10 (between 0 and 9) requires 4 bits, but there are 2 4 − 10 = 6 unused codes, so input values less than 6 have the first bit discarded, while input values greater than or equal to 6 are offset by 6 to the end of the binary space. (Unused patterns are not shown in this table.)
Dynamic web page: example of server-side scripting (PHP and MySQL). A dynamic web page is a web page constructed at runtime (during software execution), as opposed to a static web page, delivered as it is stored. A server-side dynamic web page is a web page whose construction is controlled by an application server processing server-side scripts ...
Truncation of positive real numbers can be done using the floor function.Given a number + to be truncated and , the number of elements to be kept behind the decimal point, the truncated value of x is
Suppose we have a continuous differential equation ′ = (,), =, and we wish to compute an approximation of the true solution () at discrete time steps ,, …,.For simplicity, assume the time steps are equally spaced:
Truncation (geometry) is the removal of one or more parts, as for example in truncated cube Propositional truncation , a type former which truncates a type down to a mere proposition Computer science
