SameValue

Tests if two objects are equal (with epsilon).

Syntax

• SameValue(x, y[, ε])

  • x and y are any two objects

  • ε is a positive number

Description

If x and y are any two objects, then SameValue(x, y, ε) is true iff x and y are equal, with floating-point values being compared with epsilon ε. 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.

The binary ≈ operator is implemented by the SameValue function. It will always use the default (but non-zero) epsilon.
