问题 Foreword It looks like it is a duplicate of few stackoverflow question but my situation is (probably) slightly unique. My situation I have a dictionary. The key is a string and the value is an integer . I want the python script to randomly choose N number of keys . The value is how likely it is to be chosen. The higher the key's value is, the higher the chance the key will be randomly chosen. My solution So using some other StackOverflow post and the power of the internet I managed to solve

问题 I have a set of percentages in R which I want to make equal to 100%. I need the individual percentages to be to the nearest integer. I have rounded percentages [20.5, 50.6, 25.8 , 3.1].Then I am rounding to the nearest integer [ 20,50,25,3].Then working out the individual decimal places [0.5,0.6,0.8.0.1].Then sorting the decimal places in descending order but output are [ 3,2,1,4].And I need to add 1 to the integer of the highest decimal place until I reach 100. 回答1: It is not really as

问题 May be I might be blind or silly, but look at my function: function max_min_twenty($value) { if ((int)$value == 0) { return "0"; } else { $percent_val = ((int)$value / 100) * 20; $maxvalue = (int)$value + $percent_val; $minvalue = (int)$value - $percent_val; $returnvalue = round($minvalue)."-".round($maxvalue); return $returnvalue; } } Seems that this is really easy! It works like it should, but if my $value is 1500000 it gives me back 1,2E+6 for $minvalue - It does well if I choose a
