# V615\. Suspicious explicit conversion from 'float \*' type to 'double \*' type\.

The analyzer has detected an odd pointer type conversion\. Among such strange cases are situations when programmers try to cast a float\-pointer to a double\-pointer or vice versa\. The point is that float and double types have different sizes and this type conversion most likely indicates an error\.

Consider a simplest example:

```cpp
float *A;
double* B = (double*)(A);
```

Incompatibility between the sizes of the types being cast causes 'B' to point to a number format incorrect for the double type\. Such pointer type conversion errors occur because of misprints or through inattention\. For example, it may appear that a different data type or a different pointer should be used in such a code fragment\.

This is the correct code:

```cpp
double *A;
double* B = A;
```
