The application itself may also test to see if a math coprocessor is installed. During initialization, it tests for the math coprocessor in the same way the BIOS does. In fact, it is becoming more common for applications themselves to test for the presence of the math coprocessor as well as other parameters, and then configure themselves automatically to operate with the hardware that is installed.

If no math coprocessor is present, the CPU will perform the math calculations using lengthy software instructions that emulate the math coprocessor’s built-in functions. While the emulation may occur within the operating system, it is more likely to occur within the application program. Thus, when a math coprocessor instruction is encountered, the application will execute the
