WebThe representation of floating points in JavaScript follows the format as specified in IEEE-754. Specifically it is a double-precision format, meaning that 64 bits are allocated for each floating point. Although it is not the only way to represent floating points in binary, it is by far the most widely used format. The Pentium FDIV bug is a hardware bug affecting the floating-point unit (FPU) of the early Intel Pentium processors. Because of the bug, the processor would return incorrect binary floating point results when dividing certain pairs of high-precision numbers. The bug was discovered in 1994 by Thomas R.
