Macro serde_json_lodash::x_ceil_x

macro_rules! x_ceil_x {
    () => { ... };
    ($a:expr $(,)*) => { ... };
    ($a:expr, $b:expr $(,)*) => { ... };
    ($a:expr, $b:expr, $($rest:tt)*) => { ... };
}

Based on x_ceil_x()

Examples:

#[macro_use] extern crate serde_json_lodash;
use serde_json::Number;
assert_eq!(
  x_ceil_x!(Number::from_f64(4.006).unwrap()),
  Number::from(5)
);
assert_eq!(
  x_ceil_x!(Number::from_f64(6.004).unwrap(), 2),
  Number::from_f64(6.01).unwrap()
);
assert_eq!(
  x_ceil_x!(Number::from(6040), -2),
  Number::from(6100)
);

assert_eq!(
  x_ceil_x!(),
  Number::from(0)
);
