Attention
Version 3 is now the current version of MathJax. This document is for version 2.
The AsciiMath input processor¶
The options below control the operation of the AsciiMath input
processor that is run when you include "input/AsciiMath"
in the
jax array of your configuration or load a combined configuration
file that includes the AsciiMath input jax. They are listed with
their default values. To set any of these options, include a
AsciiMath
section in your MathJax.Hub.Config()
call. For
example
MathJax.Hub.Config({
AsciiMath: {
fixphi: true,
useMathMLspacing: true,
displaystyle: false,
decimalsign: "."
}
});
would set the displaystyle
configuration option so that the limits
for operators like summation symbols will appear next to them rather
than above and below.

fixphi: true
Determines whether MathJax will switch the Unicode values for
phi
andvarphi
. If set totrue
MathJax will use the TeX mapping, otherwise the Unicode mapping.

useMathMLspacing: true
Determines whether MathJax will use MathML spacing. Set to
false
to get TeXlike spacing.

displaystyle: true
Determines whether operators like summation symbols will have their limits above and below the operators (true) or to their right (false). The former is how they would appear in displayed equations that appear on their own lines, while the latter is better suited to inline equations so that they don’t interfere with the line spacing so much.

decimalsign: "."
This is the character to be used for decimal points in numbers. if you change this to
","
, then you need to be careful about entering points or intervals. E.g., use(1, 2)
rather than(1,2)
in that case.
