Mathematica symbolic expressions can represent an immense range of types of objects. Mathematica provides a rich collection of functions to test expressions. Functions that ...

GeoProjectionData["projection", " property"] gives the value of the specified property for the specified cartographic projection.GeoProjectionData["projection"] gives the ...

Relational operators. This tests whether 10 is less than 7. The result is False. Not all of these numbers are unequal, so this gives False.

Mathematica handles formulas of all types, from polynomials with millions of terms to complex combinations of higher mathematical functions. It provides powerful general ...

Equivalent[e_1, e_2, ...] represents the logical equivalence e_1 \[DoubleLeftRightArrow] e_2 \[DoubleLeftRightArrow] ..., giving True when all of the e_i are the same.

Implies[p, q] represents the logical implication p \[DoubleRightArrow] q.

Hash[expr] gives an integer hash code for the expression expr.Hash[expr, " type"] gives an integer hash code of the specified type for expr.

Some operators used in basic arithmetic and algebra. Note that the  for ∖[Cross] is distinguished by being drawn slightly smaller than the × for ∖[Times]. Interpretation of ...

When you do calculations with arbitrary-precision numbers, Mathematica keeps track of precision at all points. In general, Mathematica tries to give you results which have ...

SameTest is an option whose setting gives a pairwise comparison function to determine whether expressions should be considered the same.
