Hi,
I tried to convert a msg.payload to return round value of the number. But the function does not return the number.
The js code is here:
module.exports = function(RED) {
function MathOPeration(config) {
RED.nodes.createNode(this,config);
var node = this;
this.operation = config.operation;
this.on('input', function(msg) {
if (typeof (msg.payload) === 'number'){
if(node.operation === "floor"){
//var x = parseInt(node.operation);
//var a = Math.floor(x);
//msg.payload = msg.payload.a;
// msg.payload = Number(msg.payload);
msg.payload = msg.payload.Math.floor(msg.payload);
}
else if(node.operation === "lower"){
msg.payload = msg.payload.toLowerCase();
}
else if (node.operation === "round"){
msg.payload = msg.payload.Math.round(node.operation);
}
else if (node.operation === "sqrt"){
var y = parseInt(node.operation);
var c = Math.sqrt(y);
msg.payload = msg.payload.c;
}
node.send(msg);
}else{
node.error("Payload not number",msg);
}
While in debug the return shows undefined. How can I get the floor value?
Regards.
