The values are quite clse to eachother so amCharts decides to hide the 0 value axis and dislay only the relevant data. This is all good, but the thing is that I need to be able compare my columns visually. I also want to hide the labels on the value axis at some point. Generally what I get now is this: As you can see, value axis starts counting from 22.5. I need it to always start counting from 0, so I can compare the columns

We initialized a 16 bit signed integer with 0x8000 (the platform is of course uses 2's complement representation for negative numbers). In a hardly reproducible special case, modulo by 10 was being performed on this variable to extract individual digits in decimal representation while the value is still 0x8000 (-32768). -32768 % 10 == 248 which makes no sense for our application. Our platform is OKI 411 micro-controller. I'm curious, though taking modulo of negative number

It works for the first array but the second one is making problems even though every thing is the same. I'm really stuck. The Code is as follows: from wordutility import wordutility from sklearn . feature_extraction . text import TfidfVectorizer from sklearn . linear_model import LogisticRegression from sklearn import cross

Permissible values are -1.7976931348623157E+308 to -2.2250738585072014E-308, 0, and 2.2250738585072014E-308 to 1.7976931348623157E+308. This doesn't make sense to me. Maybe I'm being a mathtard, but I'm not understanding this. There appears to be two possible ranges and zero. 回答1: Yes, it has a range of possible positive values, zero, and a range of possible negative values. The reason they're doing it that way is to ensure you get

Why's that? x^-1 should just be 1/x if i recall my math correctly. 回答1: In NumPy, the logic used to choose the output dtype of an operation like a_range ** s is

I'm generally decent with regular expressions, but negative lookaheads have me stumped. Why doesn't this work? /(?!foo)\.htm$/ i . test ( "/foo.htm" ); // returns true. I want false. What should I be using instead? I think I need a "negative look behind " expression (if JavaScript supported such a thing, which I know it doesn't). 回答1: The problem is pretty simple really. This will do it: /^(?!.*foo\.htm$).*\.htm$/i 回答2: What you are describing (your intention

For example, '(4,301)' to -4301, as commonly encountered in accounting applications. 回答1: The simplest way is: my_str = "(4,301)" num = - int ( my_str . translate ( None , "()," )) 回答2: Since you are reading from a system that put in thousands separators, it's worth mentioning that we are not using them the same way all around the world, which is why you should consider using a locale system. Consider: import

The w3school say to use negative number to rewind it. http://www.w3schools.com/tags/av_prop_playbackrate.asp Anyone can tell me what I did wrong? Here my javascript worked code for fast forward, $("#speed").click(function() { // button function for 3x fast speed forward video.playbackRate = 3.0; }); Then here not success rewind code, $("#negative").click(function() { // button function for rewind video.playbackRate = -3.0;
