Berkeley SoftFloat
Berkeley SoftFloat is a free, high-quality software implementation of binary floating-point that conforms to the IEEE Standard for Floating-Point Arithmetic. SoftFloat is completely faithful to the IEEE Standard, while at the same time being relatively fast. All functions dictated by the original 1985 version of the standard are supported except for conversions to and from decimal. The latest release of SoftFloat implements five floating-point formats: 16-bit half-precision, 32-bit single-precis...

Calculating the mean of a list of numbers - Hypothesis
Calculating the mean of a list of numbers Consider the following problem:

You have a list of floating point numbers. No nasty tricks - these
aren’t NaN or Infinity, just normal “simple” floating point numbers.

Now: Calculate the mean (average). Can you do it?

It turns out this is a hard problem. It’s hard to get it even close to
right. Lets see why.
