By default, the float type has 6 digits after the decimal point. If you want to output a number or other numbers, you can output them in the following form:

Printf("%。 (Enter the number of digits to be output here) f ",x);

If one bit is output: printf("%. 1f ",x);

int main()

{

?

Printf ("Maximum number of bytes stored printf("float: %lu \n", sizeof(float))；);

Printf ("floating point minimum: %E\n", FLT _ minimum); ?

Printf ("floating point maximum: %E\n", FLT _ maximum); ?

Printf ("precision value: %d\n", FLT _ dig); ?

Returns 0;
