WebIBM's compiler has an option, like GCC, to disable FMA and an option, like GCC, to enable unsafe transformations. Second, this issue should not be considered two categories (IEEE 754 and non-IEEE 754) but three categories (round every intermediate expression, excess intermediate precision, and fast-and-loose). WebThis webpage is a tool to understand IEEE-754 floating point numbers. This is the format in which almost all CPUs represent non-integer numbers. As this format is using base-2, there can be surprising differences in what numbers can be represented easily in decimal and which numbers can be represented in IEEE-754. As an example, try "0.1". traditional french madeleines recipe
