Is it possible to generate a random decimal number in javascript?

Question

I know how to generate a random integer but need to generatea number with a decimal

Answer 1

Math.random() generates a decimal number between 0 and 1.



If you want a different range, multiply and add.



If you paste this in your browser address bar and load it, it will generate a random decimal number between 100 and 200:



javascript:alert(100 + Math.random()*100)

Answer 3

Math.random() already gives a pseudorandom number from 0 to 1.



To get a random floating point number within a certain range, first define the range by 'min' and 'max', then do this:



min + (Math.random() * (max - min))



Note however that this will never generate the maximum value. It may come extremely close, but the maximum value will never be generated.



If you need it to be possible to generate the maximum value, or you need more randomness than the built-in pseudorandom generator can provide, there are ways to construct more advanced systems that reduce weaknesses like that. However, they will also take longer to run.

Answer 4

could you not just cast the integer to a data type that holds a decimal and then say divide by ten
