Custom Random Block

Hello, i came here with an idea for a "Custom Random" block:

Random between: (number slot) And: (number slot) Rounding: (logic [true/false] slot)

For example: between 5 and 10 would get you random number in between them, for example 7.

Rounding would control whether the number generated could or couldn't have a "decimal place" (0.21 for example). Here's how it would be able to generate:

With rounding:

Math.floor(Math.random(num1,num2))

Or something like that, since it causes compilation errors.

Without rounding:

(Math.random(num1,num2))

Should work like that. I can make compilation code in Java.
