Hello FlashCoder...
maybe it's because it's late but it's getting a little confusing, and google is
not being friendly right now.
seems to works fine with positive numbers, however - i am trying to normalise a
range of positive and negative numbers... ( code simplified not to find min and
max values ).
I am currently am coming up a little short... hope this code does not give
anyone a headache; if you fancy a stab, or if you can point me in the right
direction
... otherwise ... will post results when i get there...
Code:
public function test() {
trace('------------------------------------')
trace( testNormalizeNumbers( [ 1 , 1.5 , 2 ] , 2 , 1 ).toString() );
trace('------------------------------------')
trace( testNormalizeNumbers( [ 1 , 1.5 , 5 , 1 , 6.4 , 6, 3, -2.6, -1
, 3.5 ] , 6.4 , -2.6 ).toString() );
trace('------------------------------------')
trace( testNormalizeNumbers( [ -1 , -1.5 , -5 , -1 , -6.4 , -6, -3,
-2.6, -1 , -3.5 ] ,-1 , -6.4 ).toString() );
}
public function testNormalizeNumbers( a : Array , max : Number , min : Number )
: Array {
var result : Array = new Array();
var nMax : Number = ( min > 0 ) ? max - min : max +
Math.abs( min );
for ( var c : int = 0 ; c < a.length ; c++ ){
var pRangedValue : Number = ( min > 0 ) ? a[c] -
min : a[c] + Math.abs( min );
var normalizedValue : Number = pRangedValue / nMax;
result.push( normalizedValue );
}
return result;
}
Thanks
