Are there any specific considerations for MSVC to avoid unexpected truncation during such conversion

Here is the code from the editor :

#include <stdio.h>

double getDouble() {
  double value = 2147483649.0;
  return value;
}

int main() {
  unsigned int directCast;
  double d;

  printf("INT_MAX: %u\n", INT_MAX);
  printf("UINT_MAX: %u\n", UINT_MAX);

  printf("Double value: %f\n", getDouble());

  directCast = (unsigned int)getDouble();
  printf("Direct cast value: %u\n", directCast);

  d = getDouble();
  printf("Indirect cast value: %u\n", (unsigned int)d);

  return 0;
}

#include <stdio.h>

double getDouble() {
  double value = 2147483649.0;
  return value;
}

int main() {
  unsigned int directCast;
  double d;

  printf("INT_MAX: %u\n", INT_MAX);
  printf("UINT_MAX: %u\n", UINT_MAX);

  printf("Double value: %f\n", getDouble());

  directCast = (unsigned int)getDouble();
  printf("Direct cast value: %u\n", directCast);

  d = getDouble();
  printf("Indirect cast value: %u\n", (unsigned int)d);

  return 0;
}
