than the right one
It is false iff both parts are numeric and real, and left number is less or equal
the right one
It is NaN/unsimplified otherwise.

• Limitf

Summary

A node of limit
• Logf

Summary

A node of logarithm

Summary

• Minusf

Summary

A node of difference
• Mulf

Summary

A node of product
• Notf

Summary

Whatever its argument is, the result will be inverted
• Number

Summary

Number node.
This class represents all possible numerical values as a hierarchy,
NumberComplexRealRationalInteger
• Orf

Summary

Is true iff at least one operand is true,
• Phif

Summary

This node represents the Euler totient function (phi)
• Piecewise

Summary

This is a node which defined on different subsets differently. When evaluating, it will turn
into a particular case once all cases' predicates before are false, and this case's predicate is true.

That is, the order counts. An example:
Piecewise(a provided false, b provided true, c provided true)
Will be evaluated into b,

Piecewise(a provided false, b provided c, c provided false)
Will remain as it is (although unreachable cases will be removed)
• Powf

Summary

A node of exponential (power)
• Providedf

Summary

That is a node which equals Expression if Predicate is true, otherwise NaN
• Secantf

Summary

A node of secant
• Set

Summary

https://en.wikipedia.org/wiki/Set_(mathematics) A set might be a set operator, conditinal set, finite set, or interval
• Signumf

Summary

A node of signum
• Sinf

Summary

A node of sine
• Statement

Summary

This class describes every node whose value is boolean, that is, true or false.

Example

Entity t1 = "a and b"; // Statement
Entity t2 = "a > b > c"; // Statement
Entity t3 = "a or b implies x > 0"; // Statement

Entity t4 = "a"; // Not Statement
Entity t5 = "a + 3"; // Not Statement
Entity t6 = "a provided c and d"; // Not Statement
• Sumf

Summary

A node of sum
• Tanf

Summary

A node of tangent
• TrigonometricFunction

Summary

Describes any function that is related to trigonometry
• Variable

Summary

Variable node. It only has a name.
Construct a Variable with an implicit conversion from String.
It has no type, so you can substitute any value under a given variable.
• Xorf

Summary

Is true iff one operand is true
