Method: PropCheck::Generators.real_float

Defined in:
lib/prop_check/generators.rb

.real_float ⇒ Object

Generates floating-point numbers These start small (around 0) and become more extreme (large positive and large negative numbers)

Will only generate ‘reals’, that is: no infinity, no NaN, no numbers testing the limits of floating-point arithmetic.

Shrinks towards zero. The shrinking strategy also moves towards ‘simpler’ floats (like 1.0) from ‘complicated’ floats (like 3.76543).

>> Generators.real_float().sample(10, size: 10, rng: Random.new(42))
