Even better would be to leave the sign in the value for the setDiff
method. Only use abs to look for the difference with the value in the
window
float diff, searchdiff;
searchdiff = [diffinput floatValue]; // need to add a inputfield in the
window
diff = mw-theweight // distance from target mw
if (fabs(diff) <= searchdiff )
{
[peptide setDiff: diff];
[peptide setRange: aRange];
// add it to the results array, release it to counterbalance the init
as it is now retained by the array
[results addObject: peptide];
[peptide release];
// yep, we have another one screened:
counter++;
}
