# zigzag a module for [zigzag encoding](https://developers.google.com/protocol-buffers/docs/encoding#types) in JS. ```javascript var zz = require('zigzag') zz.encode32(3) zz.decode32(3) zz.encode64high(lowint, highint) zz.encode64low(lowint, highint) ``` ## API #### zz.encode32(number) -> encoded integer #### zz.encode64low(lowint, highint) -> encoded integer #### zz.encode64high(lowint, highint) -> encoded integer encodes an integer using zigzag encoding. for >32bit values, use `encode64{low,high}` to get the constituent int32 values. #### zz.decode32(number) -> decoded integer #### zz.decode64low(lowint, highint) -> decoded integer #### zz.decode64high(lowint, highint) -> decoded integer decodes a zigzag-encoded integer. for >32bit values, use `decode64{low,high}` to get the constituent int32 values. # license MIT
