TypeScript 1.8.9:
Can there be a way to limit number value for example

an property that accepts 0-255 number or decimals as shown below

eg:

interface options{
red:number[0-255];//0 to 255
count:number[0-*];//0 to infinity
opacity:number[0.0-1.0];// decimal points from 0 to 1
}

this would let users limit the options that most javascript frameworks allow

Thanks
