How do you put an Hex in IR

So I have trying to control my sound system and tv with ALEXA, i have the Alexa part nailed down, but i am having trouble with the IR side. I have a IR led on pin 3 and ground and the code for the volume down is 240C, UP is 640C, and the tv on/off code is F4BA2988. I dont know how to adjust this sample code for those values(especially the tv code)

#include <IRremote.h>

IRsend irsend;

void setup()
{
}

void loop() {
	for (int i = 0; i < 3; i++) {
		irsend.sendSony(0x240c, 12);
		delay(40);
	}
	delay(5000); //5 second delay between each signal burst
}

All help is appreciated!

I can see that your code starts with a comment, but can't see where the comment ends.

This was just a typo ill edit it out

For very large numbers such as F4BA2988, use the UL suffix to make sure it is handled as a unsigned long (32 bit value). For example, irsend(0xF4BA2988UL, ...)

thanks!
