Content elements: rationals to root

(Excerpt from "The MathML Handbook" by Pavi Sandhu)

rationals

Syntax

<rationals />

Description

The rationals element represents the set of all rational numbers, typically denoted by Q.

Attributes

This element accepts the attributes definitionURL and encoding.

real

Syntax

<apply><real /> arg1</apply>

Description

The real element represents the real part of a complex number specified as an argument.

Attributes

This element accepts the attributes definitionURL and encoding.

reals

Syntax

<apply><in /> expression <reals /></apply>

Description

The reals element represents the set of all real numbers, typically denoted by R.

Attributes

This element accepts the attributes definitionURL and encoding.

reln

Syntax

<reln> operator (argument)+</reln>

Description

The reln element is used to specify a mathematical relation, such as a = b, a < b, and a greater than or equal to b. It contains as its first child element one of the content elements that represent relations, such as eq, lt, or geq. The reln element is deprecated in MathML 2.0 since its role is now taken over by the apply element.

Attributes

This element accepts the attributes definitionURL and encoding.

rem

Syntax

<apply><rem /> dividend divisor</apply>

Description

The rem element represents the remainder of integer division. In other words, if m and n are integers, the remainder is the integer r, such that m = n * q +r, where |r| &lt; |m| and m * r &gt; 0.

Attributes

This element accepts the attributes definitionURL and encoding.

root

Syntax

<apply>
  <root />
  <degree>degree</degree>
  radical
</apply>

Description

The root element is used to take the root of a number or expression. It has two arguments. The first argument is a degree element that specifies the degree of the root. If this is omitted, a default value of 2 is assumed.

Attributes

This element accepts the attributes definitionURL and encoding.
