Exclamation What are with the Ls in Kevin's code??!!! HELP!!!
what are with the "L"s in Kevin's code?
For example,

in Reset_Gyro_Angle,
PHP Code:
gyro_angle = 0L; 
also:

in
PHP Code:
int cmd_velocity(void)
{
    // ...
mrad_per_sec = (mm_per_sec * 1000L) / WHEEL_RADIUS;
    // ...
} 
what are they?
why are they there?
where are they defined?

i'm wondering also because our gyro does not work.
see this thread for more gyro details: http://www.chiefdelphi.com/forums/sh...ad.php?t=33786

thank you for any help in advance!!

Thanks for making FIRST such a great experience for me. I'm no longer on 1351, and I'm not currently planning to mentor team 97, but FIRST has meant so much in getting me to where I am now, in life and at MIT, class of 2011.
I met Billfred! He recognized me!

Re: What are with the Ls in Kevin's code??!!! HELP!!!
The L (i.e. 97L) means that the value (97) should be stored as a Long, instead of whatever they system default is. (Word, in this case.)
