Struct Any
pub struct Any(FloatTypes);Expand description
Strategies which produce floating-point values from particular
classes. See the various Any-typed constants in this module.
Note that this usage is fairly advanced and primarily useful to
implementors of algorithms that need to handle wild values in a
particular way. For testing things like graphics processing or game
physics, simply using ranges (e.g., -1.0..2.0) will often be more
practical.
Any can be OR’ed to combine multiple classes. For example,
POSITIVE | INFINITE will generate arbitrary positive, non-NaN
floats, including positive infinity (but not negative infinity, of
course).
If neither POSITIVE nor NEGATIVE has been OR’ed into an Any
but a type to be generated requires a sign, POSITIVE is assumed.
If no classes are OR’ed into an Any (i.e., only POSITIVE and/or
NEGATIVE are given), NORMAL is assumed.
The various float classes are assigned fixed weights for generation which are believed to be reasonable for most applications. Roughly:
-
If
POSITIVE | NEGATIVE, the sign is evenly distributed between both options. -
Classes are weighted as follows, in descending order:
NORMAL>ZERO>SUBNORMAL>INFINITE>QUIET_NAN=SIGNALING_NAN.
