Per utilizzare questo servizio occorre richiamare il sito con:
- https://math.croswil.com/f?<formula> - https://math.croswil.com/fdown?<formula>
dove la formula viene costruita secondo le regole descritte sotto. La grammatica asciimath è derivata da mathjax. A dfferenza di quanto proposto dal sito di mathjax, non serve installare alcuna libreria sul client. E' sufficente richiamare questo servizio per ottenere una immagine in SVG.
le differenze tra i due modi di chiamata: (f e fdown) sono sul risultato che da una immagine SVG integrabile, nel primo caso e una immagine da scaricare nel secondo.Croswil.
Most AsciiMath symbols attempt to mimic in text what they look like
rendered, like oo
for ∞
. Many symbols can also be
displayed using a TeX alternative, but a preceeding backslash is not
required.

Matrices: [[a,b],[c,d]]
yields to [abcd]
Column vectors: ((a),(b))
yields to (ab)
Matrices can be used for layout:
{(2x,+,17y,=,23),(x,-,y,=,5):}
yields
{2x+17y=23x−y=5
Complex subscripts: lim_(N->oo) sum_(i=0)^N
yields to limN→∞N∑i=0
Subscripts must come before superscripts:
int_0^1 f(x)dx
yields to ∫10f(x)dx
Derivatives: f'(x) = dy/dx
yields f'(x)=dydx
For variables other than x,y,z, or t you will need grouping symbols:
(dq)/(dp)
for dqdp
