## Syntax

### Dollar signs as text

If you try to enter a dollar sign followed by a number, you may get unexpected results. For example:

The price of GPU compute dropped from $0.50 per GFLOPS to$0.05 per GFLOPS over ten years.

will give you:

 The price of GPU compute dropped from $0.50 per GFLOPS to$0.05 per GFLOPS over ten years.

This is because the wiki uses a plugin for interpreting mathematical symbols, and the dollar sign is used to indicate TeX code. The double percent sign escape sequence (the standard way of escaping special characters on dokuwiki), does not work. The solution is to put a backslash in front of the dollar sign or <nowiki></nowiki> tags around the dollar sign like this:

The price of GPU compute dropped from \$0.50 per GFLOPS to <nowiki>$</nowiki>0.05 per GFLOPS over ten years.

which gives the desired result:

 The price of GPU compute dropped from \$0.50 per GFLOPS to$0.05 per GFLOPS over ten years.
