Macro sec_f 

macro_rules! sec_f {
    ($x:expr) => { ... };
}

Converts a floating-point second count (Real) to total attoseconds (i128).

Sugar for Dt::sec_f_to_attos. Does not build a Dt — only converts the second count to attoseconds via the high-precision IEEE 754 path.

Example

use deep_time::{Dt, sec_f};

assert_eq!(sec_f!(1.5), Dt::sec_f_to_attos(1.5));
