Using char for custom math elements
The char expression can contain a custom math element by using the following syntax:
<MathFullForm `char[(*T"
where ElementName is the name of the reference frame that contains the custom element.
Using char and diacritical for diacritical marks
The char and the diacritical expressions both describe diacritical marks around an operand.
The char expression places diacritical marks around a single operand, as shown in the following table. The
char expression is backward-compatible.
Example
x
x ˆ
x ˜
x'
x''
x'''
x ·
x ··
x ···
x
x
˜
x
The char expression can also describe composite diacritical marks. The following table contains examples.
Example
x
x' ˜
"T*)New]'>
<MathFullForm> statement
<MathFullForm `char[x,1,0,0,0,0]'>
<MathFullForm `char[x,2,0,0,0,0]'>
<MathFullForm `char[x,3,0,0,0,0]'>
<MathFullForm `char[x,0,1,0,0,0]'>
<MathFullForm `char[x,0,2,0,0,0]'>
<MathFullForm `char[x,0,3,0,0,0]'>
<MathFullForm `char[x,0,0,1,0,0]'>
<MathFullForm `char[x,0,0,2,0,0]'>
<MathFullForm `char[x,0,0,3,0,0]'>
<MathFullForm `char[x,0,0,0,1,0]'>
<MathFullForm `char[x,0,0,0,0,1]'>
<MathFullForm `char[x,0,0,0,0,2]'>
MathFullForm statement
<MathFullForm `char[x,1,0,0,0,2]'>
<MathFullForm `char[x,3,1,0,0,2]'>
