Javascript creates pseudo-random numbers with the function Math. random() . This function takes no parameters and creates a random decimal number between 0 and 1. The returned value may be 0, but it will never be 1.
Math. random() as is will generate a random float number between 0.0 and 1.0 . From 0 inclusive to 1 exclusive.
The random. uniform() function is perfectly suited to generate a random number between the numbers 0 and 1, as it is utilized to return a random floating-point number between two given numbers specified as the parameters for the function.
For rand() / RAND_MAX it means that 1 is actually a possible result, though because of integer division, 0 is the only other possible result.
You can use Math.round(Math.random()). If Math.random() generates a number less than 0.5 the result will be 0 otherwise it should be 1.
There is a +1 with Math.random, so it will always going to add 1 to the randomly generated number.
You can just randomly generate a number, since Math.random will generate any floating number between 0 & 1, then use if.. else to assign 0 or 1
var y = Math.random();
if (y < 0.5)
y = 0
else
y= 1
console.log(y)If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
