             Summary: Create a set of default functions
                 Key: TINKERPOP-1632
                 URL: https://issues.apache.org/jira/browse/TINKERPOP-1632
             Project: TinkerPop
          Issue Type: Improvement
          Components: process
    Affects Versions: 3.3.0
            Reporter: Daniel Kuppitz


We already have a a set of default BiFunctions / operators, that are not 
treated as lambdas. We should also have a bunch of simple functions, that can 
then be used in {{map()}} or {{sack()}} and that can be serialized as bytecode. 
For example:

{noformat}
...map(sqrt)
...map(log)
...sack(sigmoid)     // compute sigmoid of the current sack and update the sack
...sack(cos).by("x") // compute the cosine of the current element's "x" and 
assign / overwrite the current sack value
{noformat}
