Do I really have to cast float to uint8_t if I just want to convert 203.0 to 203 at a microcontroller?

Question

In computers, it's OK to use float as an argument where the argument should actually be a uint8_t
void myFunction(uint8_t myVal);

But what if I call this function myFunction(value); where value is of datatype float inside a microcontroller? The microcontroller have single precision included. The variable value have its range from 0 to 250 in this case.
Do I need to call my function myFunction((uint8_t) value) ?

No need to do explicit cast, the compiler knows what to do implicitly, just like when you assign the float to an integer variable for example.
