zigzag

a module for zigzag encoding in JS.

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.
