Meaning of code

[MBB]

I'm using a BME280 Humidity and pressure sensor.

In the Compensation Formulas there these two line of code :

v_x1_u32r = (v_x1_u32r < 0 ? 0 : v_x1_u32r)

v_x1_u32r = (v_x1_u32r > 419430400 ? 419430400 : v_x1_u32r)

Does anyone know what this means?

Yes, see below.

There is a library for the BME280. Not working for you? Mike Otte wrote one a while ago. See the demo for BT_BME280_16F1705_V1_00.GCB

v_x1_u32r = (v_x1_u32r < 0 ? 0 : v_x1_u32r)

Conversion

if  (v_x1_u32r < 0) then
    v_x1_u32r = 0
 else
    v_x1_u32r = v_x1_u32r
end if

can be optimised to

if  v_x1_u32r < 0 then v_x1_u32r = 0

---

v_x1_u32r = (v_x1_u32r > 419430400 ? 419430400 : v_x1_u32r)

Conversion

if (v_x1_u32r > 419430400) Then
    v_x1_u32r = 419430400
else
    v_x1_u32r = v_x1_u32r;
End If

can be optimised to

if (v_x1_u32r > 419430400) Then  v_x1_u32r = 419430400

Thanks!
