A very late reply, but just in case someone needs a ready function for this: scipy.stats.linregress i.e. slope, intercept, r_value, p_value, std_err = scipy.stats.linregress(x, y) as in @Adam Marples’s answer.
You’re using Python 2.x, where integer divisions will truncate instead of becoming a floating point number. >>> 1 / 2 0 You should make one of them a float: >>> float(10 – 20) / (100 – 10) -0.1111111111111111 or from __future__ import division, which the forces / to adopt Python 3.x’s behavior that always returns … Read more
value = Math.Truncate(100 * value) / 100; Beware that fractions like these cannot be accurately represented in floating point.
Traditionally by megabyte we mean your second option — 1 megabyte = 220 bytes. But it is not correct actually because mega means 1 000 000. There is a new standard name for 220 bytes, it is mebibyte (http://en.wikipedia.org/wiki/Mebibyte) and it gathers popularity.
Math.abs(num) => Always positive -Math.abs(num) => Always negative You do realize however, that for your code if($this.find(‘.pdxslide-activeSlide’).index() < slideNum-1){ slideNum = -slideNum } console.log(slideNum) If the index found is 3 and slideNum is 3, then 3 < 3-1 => false so slideNum remains positive?? It looks more like a logic error to me.
With Swift 3 & 4, pi is now defined as a static variable on the floating point number types Double, Float and CGFloat, so no specific imports are required any more: Double.pi Float.pi CGFloat.pi Also note that the actual type of .pi can be inferred by the compiler. So, in situations where it’s clear from … Read more
Here is a javascript function: function measure(lat1, lon1, lat2, lon2){ // generally used geo measurement function var R = 6378.137; // Radius of earth in KM var dLat = lat2 * Math.PI / 180 – lat1 * Math.PI / 180; var dLon = lon2 * Math.PI / 180 – lon1 * Math.PI / 180; var … Read more
There is a difference between modulus and remainder. For example: -21 mod 4 is 3 because -21 + 4 x 6 is 3. But -21 divided by 4 gives -5 with a remainder of -1. For positive values, there is no difference.
There are only 3% of numbers between 1 and 230 which are NOT between 225 and 230. So, this sounds pretty normal 🙂 Because 225 / 230 = 2-5 = 1/32 = 0.03125 = 3.125%
When you divide two int’s into a floating point value the fraction portion is lost. If you cast one of the items to a float, you won’t get this error. So for example turn 10 into a 10.0 double returnValue = (myObject.Value / 10.0);
