SMA calculation seems incorrent

[hungchai]

The output of SMA(10) is 135.5, and it is wrong.
But I used the same json data to find SMA10 by python talib module , the output is 135.91 and it is correct.

Here is my test script

var talib = require('talib');
var util = require('util');
console.log("TALib Version: " + talib.version);
// var request = require('request');


var marketData = {
"c": [
    130.7,
    131.0,
    127.3,
    129.3,
    135.5,
    139.7,
    139.6,
    142.0,
    142.1,
    141.9
]
};
talib.execute({
    name: "SMA",
    startIdx: 0,
    endIdx: marketData.c.length-1,
    inReal:marketData.c,
    optInTimePeriod: 10
}, function (result) {
    var outreal = result.result.outReal;
    console.log("SMA(10) Function Results:");
    console.dir(outreal.pop());

});

output is

TALib Version: 1.0.0
SMA(10) Function Results:
135.5
