≈ (almost equal to)
Tests if two objects are equal (with epsilon).
Syntax

x ≈ y

x
andy
are any two objects

Description
If x
and y
are any two objects, then x ≈ y
is true
iff x
and y
are equal, with floatingpoint values being compared with a default but nonzero 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.
Hence, while sin(π) = 0
might be false
, sin(π) ≈ 0
will be true
.
The ≈
operator is implemented by the SameValue
function.
Examples
'(0, 1, 2, 3) ≈ '(sin(π), 1, 2, 3)
true
