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: $[ \frac{\hbar^2}{2m}\nabla^2\Psi + V(\mathbf{r})\Psi = -i\hbar \frac{\partial\Psi}{\partial t}$

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

# ​​​​$\int e^{x^2}$​

## ​​​​$\int e^{x^2}$​

$\int e^{x^2}$
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.
