For dates from 1 January 1970 onward only! This template returns the difference in days (possibly with decimals) between two dates in the Gregorian calendar. The return value is positive if date2 comes after date1 , and is negative if date2 comes before date1 (i.e. the template computes date2 - date1 ).
This is a feature of C# 7.1. Asynchronous Tasks can be awaited in the Main method by declaring it to return type Task. staticasyncTaskMain(string[]args){awaitDoWorkAsync(42);} All the combinations of Task, or Task<int>, and with, or without, the string [] args parameter are supported.
Tuples – .NET Framework 4.0 but it becomes popular when C# 7.0 introduced a new tuple type with language support [100] Nested functions – C# 7.0 [100] Pattern matching – C# 7.0 [100] Immutability – C# 7.2 readonly struct C# 9 record types [101] and Init only setters [102] Type classes – C# 12 roles/extensions (in development [103])
The American mathematician Richard Hamming pioneered this field in the 1940s and invented the first error-correcting code in 1950: the Hamming (7,4) code. [5] FEC can be applied in situations where re-transmissions are costly or impossible, such as one-way communication links or when transmitting to multiple receivers in multicast.
Lucas numbers have L 1 = 1, L 2 = 3, and L n = L n−1 + L n−2. Primefree sequences use the Fibonacci recursion with other starting points to generate sequences in which all numbers are composite. Letting a number be a linear function (other than the sum) of the 2 preceding numbers. The Pell numbers have P n = 2P n−1 + P n−2.

(), where (2n − 1)!! is the double factorial of (2n − 1), which is the product of all odd numbers up to (2n − 1). This series diverges for every finite x , and its meaning as asymptotic expansion is that for any integer N ≥ 1 one has erfc x = e − x 2 x π ∑ n = 0 N − 1 ( − 1 ) n ( 2 n − 1 ) ! !
