Java/Android: Increment Algorithm

Question

I have a value of Android accelerometer x axis, and on every 0.18 change of that value, the value of az should also be incrementally/decrementally changed by 5

for example:

at x=0, az=0

at x=0.18, az=5

at x=0.36, az=10

if the value of x back to 0.18, so az value must also be back to 5 (that means x and az are synchronized)

How should I implement this logic into codes?

PS: I expect "for", "if", or maybe "while" statements here

Sorry for my bad English. Thank you in advance

Answer 1

I presume you have some way of continually monitoring the x value. In which case, pseudo-code:

private static final double xToAz = 5.0/0.18;    

onChange(x)
{        
    az = xToAz * x;
    az -= az%5;
}
