// 计算字符串公式的值比如 1*50 计算结果为 50
function GetEval() {
    this.name = 'geteval';
    this.maxArgs = 1;
    this.minArgs = 1;
}
GetEval.prototype = new GC.Spread.CalcEngine.Functions.Function();
GetEval.prototype.evaluate = function(args) {
    debugger ;//调试用的
    try {
        var param = eval(arguments[0] == null ? "0" : arguments[0].replace("=", ""));
    } catch (error) {
        var param = 0;
    }

    return param;
}

GC.Spread.CalcEngine.Functions.defineGlobalCustomFunction("geteval", new GetEval());
