Programming motors on FTC Robot, does double effect anything or doesn’t matter?
double FORWARD_SPEED = 0.4
while (true){
frMotor.setPower(FORWARD_SPEED);
}
VS
while (true){
frMotor.setPower(0.4);
}
Right now motors tend to turn on faster than others. I’m new to Java compared to lua/python

Helper please have a look, thanks.

...
both of these are double values
0.4 is a "literal"
which i think you are confusing with "integer"
integers are 0, 1, 2, 3, ...

Oh, so doubling it doesn’t matter?
What would happen if I do float instead of double?

its both a double value, regardless whether you explicitly specify it in a variable.
If this value a constant and always used in this place I would change it to
private static final double FORWARD_SPEED = 0.4
Otherwise it being initialized every time you create an instance of this class.
And if you question why I suggest this, you can read up on "magic numbers"

what do you mean by this?
double is kinda a strange name for floating point number, but its the one to use

nothing would happen but you'd have a narrower range of numbers you can use? honestly just ignore float

double is a double precision floating point number according to the IEEE 754 standard.
float is a single precision floating point number
