The nerd’s guide to Dropbox Paper

LaTeX support

Dropbox Paper has support for inline LaTeX math like this. The Schrodinger equation comes after this word: [22m2Ψ+V(r)Ψ=iΨt[ \frac{\hbar^2}{2m}\nabla^2\Psi + V(\mathbf{r})\Psi = -i\hbar \frac{\partial\Psi}{\partial t}

You just put your equation in between two $ signs as below:
$$[ \frac{\hbar^2}{2m}\nabla^2\Psi + V(\mathbf{r})\Psi = -i\hbar \frac{\partial\Psi}{\partial t}$$

However, the math can be disappointingly small, and there doesn’t seem to be a way to make it larger.

The best technique I’ve tried is to create a header and the put the LaTeX in it

ex2\int e^{x^2}

ex2\int e^{x^2}

ex2\int e^{x^2}
with the above code looking like:
# $$ \int e^{x^2} $$
## $$ \int e^{x^2} $$
### $$ \int e^{x^2} $$
 

Syntax highlighting

As you may have noticed above, Dropbox Paper has syntax-highlighted code blocks. Below is the the cleaned example of the Fast Inverse Square Root.

float Q_rsqrt( float number )
{
        long i;
        float x2, y;
        const float threehalfs = 1.5F;

        x2 = number * 0.5F;
        y  = number;
        i  = * ( long * ) &y;                       // evil floating point bit level hacking
        i  = 0x5f3759df - ( i >> 1 );               // what the fuck? 
        y  = * ( float * ) &i;
        y  = y * ( threehalfs - ( x2 * y * y ) );   // 1st iteration
//        y  = y * ( threehalfs - ( x2 * y * y ) );   // 2nd iteration, this can be removed

        return y;
}


To do this, surround the above code with the ``` character as below:
```
insert your code here
```

Dropbox Paper will do its best to detect the proper syntax highlighting, but you will often want a different choice.
