Number -- the class of all numbers

Types of number :

• CC -- the class of all complex numbers
• CCC -- high-precision complex numbers
• QQ -- the class of all rational numbers
• RR -- the class of all real numbers
• RRR -- high-precision real numbers
• ZZ -- the class of all integers

Functions and methods returning a number :

• contract(Number,Number), see contract(Matrix,Matrix) -- contract a matrix by a matrix

Methods that use a number :

• conjugate(Number), see conjugate(CC) -- complex conjugate
• contract(Matrix,Number), see contract(Matrix,Matrix) -- contract a matrix by a matrix
• contract(Number,Matrix), see contract(Matrix,Matrix) -- contract a matrix by a matrix
• contract(Number,RingElement), see contract(Matrix,Matrix) -- contract a matrix by a matrix
• contract(Number,Vector), see contract(Matrix,Matrix) -- contract a matrix by a matrix
• contract(RingElement,Number), see contract(Matrix,Matrix) -- contract a matrix by a matrix
• contract(Vector,Number), see contract(Matrix,Matrix) -- contract a matrix by a matrix
• isUnit(Number), see isUnit -- whether a ring element is a unit
• Number * Vector -- missing documentation
• ring(Number), see ring -- Get the associated ring of an object
• substitute(Number,Ring) -- missing documentation

For the programmer

The object Number is a type, with ancestor class Thing.
