The binary representation of the integer changes. Depending on
the numerical value of the integer, some round-off error could
be introduced,

To see the binary representations, try something like

long int i;
float j;

i = 27;
j = (float) i;

printf("Integer bit pattern: %x\n",&i);
printf("Float bit pattern: %x\n\n",&j);
printf("Numerical value of float: %4.12g");
