Integer Division
1000/3600 = 0
You should change them to floats (90f
) or doubles (90.0
)
문제
I'm trying to output a really simple value, but what I obtain is really weird:
Log.d("try", "distanceWithMaxSpeed > " + ((90 * (1000 / 3600)) * ((3000 - 2000)/1000)) );
I get 0 instead of 25! Where am I wrong?

다른 팁
You're doing integer division. If the numerator is less than the divisor, then at least one of the operands should be a double
:
Log.d("try", "distanceWithMaxSpeed > " + ((90 * (1000.0 / 3600)) * ((3000 - 2000)/1000)) );
