注意: JavaScript遵循IEEE-754标准来解决可能产生意外结果的浮点值。

[lower=0] (number): The lower bound. [upper=1] (number): The upper bound. [floating] (boolean): Specify returning a floating-point number. (number): Returns the random number.
_.random(0, 5); // => an integer between 0 and 5 _.random(5); // => also an integer between 0 and 5 _.random(5, true); // => a floating-point number between 0 and 5 _.random(1.2, 5.2); // => a floating-point number between 1.2 and 5.2
