This is where some 95% of all would-be embedded programmers misusing floating point fail. ... The most fundamental one is that FP arithmetic is non-associative, (a+b)+c is not equal to a+(b+c). Imagine a=1,b= … WebJul 11, 2013 · Floating point are not real numbers, this means that the following three formulas can yield a slightly different result: a + (b + c) != (a + b) + c Floating point will be deterministic if you always do (a + b) + c in all your platforms; or if you do a + (b + c) in all of them. But as soon as it start to mix hell breaks loose.

In computing, octuple precision is a binary floating-point -based computer number format that occupies 32 bytes (256 bits) in computer memory. This 256- bit octuple precision is for applications requiring results in higher than quadruple precision. This format is rarely (if ever) used and very few environments support it.
