BIT_SIZE
— Bit size inquiry function ¶RESULT = BIT_SIZE(I)
BIT_SIZE(I)
returns the number of bits (for integers, the precision
plus the sign bit) represented by the type of I. The result of
BIT_SIZE(I)
is independent of the actual value of I.
Inquiry function
I | The type shall be INTEGER or UNSIGNED . |
The return value is of type INTEGER
program test_bit_size integer :: i = 123 integer :: size size = bit_size(i) print *, size end program test_bit_size
Fortran 90 and later, extension for UNSIGNED
(see Unsigned integers)
