The motherboard also had space for an optional 80287 math coprocessor.

The judge's ruling Friday limited the verdict to the 80287, a math coprocessor for the 286 chip, which is no longer in great demand.

The Intel 8087 was the standard math coprocessor for the 8086 and 8088, operating on 80-bit numbers.

Three of the four major math coprocessors were lost; the graphics processor could double for one of them.

The Elf II used a simple and low-cost math coprocessor.

In later Nx586's, a x87 math coprocessor was included on-chip.

Floating-point calculations were done on separate, dedicated hardware, usually in the form of a math coprocessor.

A math coprocessor compatible with the Intel 80287 or 80387 is recommended.

The 80287 (i287) was the math coprocessor for the Intel 80286 series of microprocessors.

Microcontrollers typically do not have a math coprocessor, so floating point arithmetic is performed by software.
