this could be faster ..
else {
var range = max - min
for (i = offset; i < l; i+=dim) {
if (!isNaN(arr[i])) {
arr[i] = range === 0 ? .5 : (arr[i] - min) / range
}
}
}
like
else if (min == max) {
for (i = offset; i < l; i+=dim) {
if (!isNaN(arr[i])) {
arr[i] = .5
}
}
}
else if (min == 0) {
for (i = offset; i < l; i+=dim) {
arr[i] = arr[i] / range
}
}
else {
for (i = offset; i < l; i+=dim) {
arr[i] = (arr[i] - min) / range
}
}
the NaN test is not needed, since NaN / range
and (NaN - min) / range
always equal NaN
