The library comprises several modules (corresponding to classes in an object- oriented implementation). Each module has a header file (for example, decNumber.h ) which defines its data structure, and a source file of the same name (e.g., decNumber.c ) which implements the operations on ...
In the computer system, ALU is a main component of the central processing unit, which stands for arithmetic logic unit and performs arithmetic and logic operations. It is also known as an integer unit (IU) that is an integrated circuit within a CPU or GPU, which is the last component to...
In addition to the basic arithmetic operations (add, subtract, multiply, divide, square root), common transcendental functions such as the exponential, logarithm, trigonometric and hyperbolic functions are also included. A detailed description of the algorithms used is available in the docs subdirectory...
In the below awk script, it matches last field of all lines containing the pattern /bin/sh. Regular expression should be closed between //. So all the frontslash(/) has to be escaped in the regular expression. When a line matches variable ‘n’ gets incremented by one. Printed the valu...
