# Weird behaviour when using two (2) $signs? [duplicate] Over at Worldbuilding I posted this answer and included: * Build a$1 Billion home ([Mukesh Ambani](https://en.wikipedia.org/wiki/Antilia_(building)))
* Build a $1.2 Billion Yacht ([Roman Abramovich](https://en.wikipedia.org/wiki/Eclipse_(yacht)))  and that came out as: whereas here it comes out just fine: I got around that by using USD instead of $ and tested on Ask Ubuntu, Cooking and it seems to be limited to Worldbuilding, but obviously, I don't have an account everywhere...

• @ɪʙᴜɢ: Thanks for the edit! :-) Forgot about that! – Fabby Sep 13 '18 at 1:49
• Also note that this is the wrong syntax for American dollars: the correct syntax is "$1.2 billion". – Sonic the Stay-Home Hedgehog Sep 13 '18 at 1:57 • @SonictheInclusiveHedgehog Thanks! Editing both here and there! – Fabby Sep 13 '18 at 1:58 ## 1 Answer That site has MathJax enabled so dollar signs are considered as delimiters of math blocks. See List Item 38 of this answer. Use \$ if you want a literal dollar sign instead of denoting a math block.

• Ah, Sorry to have asked a dumb question and thanks for the answer. I can only accept in 11 minutes. +1 already and my answer edited in the mean time as well. :-) – Fabby Sep 13 '18 at 1:08
