Standard:

Fortran 95 and later

Class:

Inquiry function

Syntax:

RESULT = BIT_SIZE(I)

Arguments:

I	The type shall be INTEGER.

Return value:

The return value is of type INTEGER

Example:

          program test_bit_size
              integer :: i = 123
              integer :: size
              size = bit_size(i)
              print *, size
          end program test_bit_size
