ieee754

Low-level manipulations of IEEE754 floating-point numbers.

This library includes:

• no_std support by default,
• ulp computation (units in the last place, representing the resolution of a float),
• miscellaneous functions like nextafter (next and prev), copysign (copy_sign), abs, sign,
• the IEEE-754 totalOrder predicate for doing Ord::cmp-like comparisons on floats,
• an iterator over every floating point value in a range,
• a parallel iterator over every floating point value in a range (optional: activate with the rayon feature),
• relative error computation.
