Initialisation of arrays of floats

[misra-c]

{ 0 } is a MISRA-C 2012 exception, which permits the initialization of the elements of any array to zero.
Initialisating an array of double with { 0.0 } is non-compliant, unless the array has only one element.

Code:

float64_t array_a[10] = { 0.0 };                     // non-compliant
float64_t array_a[10] = { 0 };                       // compliant
float64_t array_a[10] = { 0.0, 0.0, 0.0, 0.0, 0.0,
                          0.0, 0.0, 0.0, 0.0, 0.0};  // compliant
