[−][src]Function libmodbus::set_float_dcba

pub fn set_float_dcba(src: f32, dest: &mut [u16])

set_float_dcba - set a float value in 2 registers using DCBA byte order

The set_float_dcba() function shall set a float to 4 bytes in swapped bytes Modbus format (DCBA insted of ABCD). The dest slice must contain two u16 values to be able to store the full result of the conversion.

Parameters

  • src - float to 4 bytes (f32)
  • dest - slice must contain two u16 values

Examples

use libmodbus::prelude::*;
let mut dest = vec![0; 2];
set_float_dcba(123456.0, &mut dest);

assert_eq!(&dest, &[0x47F1, 0x2000]);
