NAME

TINY(3) - [NUMERIC MODEL] Smallest positive number of a real kind

SYNOPSIS

result = tiny(x) 

         real(kind=KIND) function tiny(x)


          real(kind=KIND) :: x

CHARACTERISTICS

o X may be any real scalar or array
o the result has the same type and kind as X

DESCRIPTION

TINY(3) returns the smallest positive (non zero) number of the type and kind of X.

For real X 

       result = 2.0**(minexponent(x)-1)

OPTIONS

o X : The value whose kind is used to determine the model type to query

RESULT

The smallest positive value for the real type of the specified kind.

EXAMPLES

Sample program: 

    program demo_tiny
    implicit none
       print *, ’default real is from’, tiny(0.0), ’to’,huge(0.0)
       print *, ’doubleprecision is from ’, tiny(0.0d0), ’to’,huge(0.0d0)
    end program demo_tiny
Results: 

     default real is from 1.17549435E-38 to 3.40282347E+38
     doubleprecision is from 2.2250738585072014E-308 to
     1.7976931348623157E+308
