Tests if two objects are equal (with epsilon).
SameValue(x, y[, ε])
yare any two objects
εis a positive number
y are any two objects, then
SameValue(x, y, ε) is
y are equal, with floating-point values being compared with epsilon
SameValue should be used to compare numeric objects such as numbers, vectors, matrices, and lists containing such elements; not all object types support epsilon comparison.
If omitted, a default (but non-zero) epsilon will be used.
≈ operator is implemented by the
SameValue function. It will always use the default (but non-zero) epsilon.
