Equal

Alternate names

equality testing | zero testing

Basic definition

Two quantities are said to be equal if they are, in some well-defined sense, equivalent. Equality of quantities a and b is written a = b.

Detailed definition

Two quantities are said to be equal if they are, in some well-defined sense, equivalent. Equality of quantities a and b is written a = b. Equal is implemented in the Wolfram Language as Equal[A, B, ...], or A==B==.... Equality of multiple expressions is commonly denoted a | = | b | = | c, which is equivalent to a = b = c. Equality is transitive, so if a = b and b = c, then it is also true that a = c.
