<MATH_CHAR>

Creates a special mathematical symbol.

Format

<MATH_CHAR> (keyword)

ARGUMENTS

keyword

Indicates the special symbol you want to access. The keywords, and the symbols they produce, are listed in Table 1-3.

related tags

restrictions

Invalid in headings, that is, within an argument to a <HEADN> tag.

The characters produced using the <MATH_CHAR> tag are sized only for normal text sizes. Therefore, these characters do not produce good visual results in text that requires a different font size, like header levels, text in the OVERHEADS doctype, and so on.

DESCRIPTION

The <MATH_CHAR> tag creates a special mathematical symbol. Table 1-3 summarizes the keywords and special symbols you can access with the <MATH_CHAR> tag.

Example

The following example lists math expressions using the <MATH_CHAR> tag. 

<LIST>(SIMPLE) 
<le><MATH>(x=y>z) 
<le><MATH>(x:=y) 
<le><MATH>(x<math_char>(leq)y<math_char>(not_eq)z) 
<le><MATH>(x<math_char>(sim)y<math_char>(simeq)z) 
<le><MATH>(x<math_char>(equiv)y<math_char>(not_equiv)z) 
<le><MATH>(x<math_char>(subset)y<math_char>(subseteq)z) 
<ENDLIST>

This example produces the following output:
