||||
real(4), parameter :: eps4 = 0.000001_4
|
||||
real(8), parameter :: eps8 = 0.000000000000001_8
|
||||
|
||||
! These eps have been set so that constant folding of intrinsic
|
||||
! functions that use host runtime can be tested independently of
|
||||
! the underlying math library used.
|
||||
! C++ <cmath> and libpgmath precise, relaxed and fast libraries pass the test.
|
||||
! It may have to be relaxed to pass on all architectures.
|
||||
! The purpose is to check that the "correct" runtime functions are mapped
|
||||
! to intrinsic functions but not to test the stability between different libraries.
|
||||
! The eps should just be low enough to give confidence that intrinsic
|
||||
! functions are mapped to runtime functions implementing the same math
|
||||
! function.
|
||||
! Compared values were selected to be around 1 +/- 0.5 so that eps is meaningful.
|
||||
! Expected values come from libpgmath-precise for Real(4) and Real(8) and
|
||||
! were computed on X86_64.
