6.6.2.3 Converting real to float
If the raw value of the module contains real type, convert these values to a float data type.
The following examples show converting real to float with C and Python.
Example: converts real to float with C
/**
* @brief Convert IEEE754 floating point.
*/

int power_count = -1;
double mantissa_int = 0;
for (int i = 0; i < 23; i++) {
mantissa_int += ((mantissa >> (22 - i)) & 1) * pow(2,
power_count);
