≈ (almost equal to)
Tests if two objects are equal (with epsilon).
x ≈ y
yare any two objects
y are any two objects, then
x ≈ y is
y are equal, with floating-point values being compared with a default but non-zero epsilon.
≈ should be used to compare numeric objects such as numbers, vectors, matrices, and lists containing such elements; not all object types support epsilon comparison.
For numeric objects,
x ≈ y differs from
x = y because of this epsilon.
sin(π) = 0 might be
sin(π) ≈ 0 will be
≈ operator is implemented by the
'(0, 1, 2, 3) ≈ '(sin(π), 1, 2, 3)
