NAME
RANGE(3) - [NUMERIC MODEL] Decimal exponent range of a numeric kind
SYNOPSIS
result = range(x)
integer function range (x)TYPE(kind=KIND),intent(in) :: x
CHARACTERISTICS
o X may be of type integer, real, or complex. It may be a scalar or an array. o KIND is any kind supported by the type of X o the result is a default integer scalar
DESCRIPTION
RANGE(3) returns the decimal exponent range in the model of the type of X.
Since X is only used to determine the type and kind being interrogated, the value need not be defined.
OPTIONS
o X : the value whose type and kind are used for the query
RESULT
Case (i) : For an integer argument, the result has the value
int (log10 (huge(x)))Case (ii) : For a real argument, the result has the value
int(min (log10 (huge(x)), -log10(tiny(x) )))Case (iii) : For a complex argument, the result has the value
range(real(x))
EXAMPLES
Sample program:
program demo_range use,intrinsic :: iso_fortran_env, only : dp=>real64,sp=>real32 implicit none real(kind=sp) :: x(2) complex(kind=dp) :: y print *, precision(x), range(x) print *, precision(y), range(y) end program demo_rangeResults:
> 6 37 > 15 307
