<code>-':</code>

'''Description:''' Function to find the differences between members of an array. Comes in various flavors.

'''Examples'''

<code>-':1 2 3 4 -> 1 1 1 1 /the builtin eachp prepends an array with zero before evaluation, so the output is the same size</code>

<code>-':5 2 4 8 -> 5 -3 2 4</code>

<code>{y/(1_;-1_)@\:x}[6 7 8;-] -> 1 1 /you can substitute the default eachp with your own for different behaviour, like this shakti example that just evaluates over each pair in x without prepending 0</code>

<code>/the difference is highlighted here:

-':6 7 8 -> 6 1 1</code>

'''Dialects''': all, syntax may vary

'''Primitives''': [[eachp]], [[minus]]
