What is the difference between precision and scale?
Apr 16, 2011 — Precision is the total number of digits, can be between 1 and 38. Scale is the number of digits after the decimal point, may also be set as negative for rounding. And Scale is the number of digits to the right (positive) or left (negative) of the decimal point, not just after the decimal point. Look at koljaTM's example.
What is the default Precision and Scale for a Number in Oracle?
Feb 27, 2009 — You can easily give a counter example: create table ex(n number); insert into ex(n) values(1.5); select * from ex; You get back 1.5. With scale=0 you would get back 1. This is also documented, e.g. with 11.2 Oracle documents that just NUMBER (without precision and without scale) results in 'maximum range and precision'. – maxschlepzig.
Number format in Oracle SQL - Stack Overflow
Jul 18, 2013 — NUMBER. To declare integers, which have no decimal point, use this form: NUMBER (precision) -- same as NUMBER (precision,0) You cannot use constants or variables to specify precision and scale; you must use integer literals. The maximum precision of a NUMBER value is 38 decimal digits.
Round to 5 (or other number) in Python - Stack Overflow
Feb 16, 2010 — Python 3. def myround(x, base=5): return base * round(x/base) It is easy to see why the above works. You want to make sure that your number divided by 5 is an integer, correctly rounded. So, we first do exactly that (round(x/5)), and then since we divided by 5, we multiply by 5 as well. I made the function more generic by giving it a base ...
Getting random numbers in Java - Stack Overflow
May 5, 2011 — random() method returns a random number between 0.0 and 0.9..., you multiply it by 50, so upper limit becomes 0.0 to 49.999... when you add 1, it becomes 1.0 to 50.999..., now when you truncate to int, you get 1 to 50. (thanks to @rup in comments). leepoint's awesome write-up on both the approaches. 2. Using Random class in Java.
How do I interpret precision and scale of a number in a database?
Numeric precision refers to the maximum number of digits that are present in the number. ie 1234567.89 has a precision of 9. Numeric scale refers to the maximum number of decimal places. ie 123456.789 has a scale of 3. Thus the maximum allowed value for decimal (5,2) is 999.99. edited Jan 27, 2013 at 16:03.
How do I generate random integers within a specific range in Java ...
int result = r.nextInt(upperBound-lowerBound) + lowerBound; This gives you a random number in between 1 (inclusive) and 11 (exclusive), so initialize the upperBound value by adding 1. For example, if you want to generate random number between 1 to 10 then initialize the upperBound number with 11 instead of 10.
Calculating bits required to store decimal number
Dec 21, 2022 — You have R symbols for a representation and you want to know how many bits, solve this equation R=2^n or log2 (R)=n. Where n is the numbers of bits and R is the number of symbols for the representation. For the decimal number system R=9 so we solve 9=2^n, the answer is 3.17 bits per decimal digit.
HTML5 Number Input - Always show 2 decimal places
Mar 25, 2014 — Is there's any way to format an input[type='number'] value to always show 2 decimal places? Example: I want to see 0.00 instead of 0.
Generating random whole numbers in JavaScript in a specific range
Oct 7, 2009 — For example, take random(2,5). We multiply the random number 0≤x<1 by the range (5-2=3), so we now have a number, x where 0≤x<3. In order to force the function to treat both the max and min as inclusive, we add 1 to our range calculation: Math.random()*(max-min+1). Now, we multiply the random number by the (5-2+1=4), resulting in an number ...
