Normal letters and standard symbols are typeset simply by using the
letters directly or using a command that denotes the wanted symbol. So
63 will produce #math80##tex2html_wrap_inline1442#Ai. The typeface chosen
will depend on the current 〈<#486#> -1
math version〉<#486#>. You can switch
between 〈<#487#>#tex2html_accent_inline1446#<#487#> outside of math mode,#tex2html_accent_inline1449# thereby changing the overall layout of the
following formulas.
LATEX<#233#><#233#> knows about two versions called `normal' and `bold'. As the
name indicates, 64 is the default. In contrast,
the bold version will produce bolder letters and symbols. This might
be suitable in certain situations like headings,
but recall that changing the
version means changing the appearance (and perhaps the meaning)
of the whole formula.
If you want to bolden only some symbols or characters within
one formula you should not change the 65.
Instead you should
define a special math alphabet for characters
(see below) and/or use the command 66 which is
provided by the document style option <#234#>#tex2html_accent_inline1451#<#234#>.
For historical reasons LATEX<#235#><#235#> maintains two abbrevations to switch
to its math versions: 67 and 68.
Other versions could be provided in special style options. For
example the `<#236#>#tex2html_accent_inline1452#<#236#>' option mentioned before sets up
a version called `euler' to typeset formulas in the same way as it
was done in~[#ConcreteMath##1###].
