dlaisnan.f(3) LAPACK dlaisnan.f(3)
NAME
dlaisnan.f -
SYNOPSIS
Functions/Subroutines
LOGICAL function dlaisnan (DIN1, DIN2)
DLAISNAN tests input for NaN by comparing two arguments for inequality.
Function/Subroutine Documentation
LOGICAL function dlaisnan (double precisionDIN1, double precisionDIN2)
DLAISNAN tests input for NaN by comparing two arguments for inequality.
Purpose:
This routine is not for general use. It exists solely to avoid
over-optimization in DISNAN.
DLAISNAN checks for NaNs by comparing its two arguments for
inequality. NaN is the only floating-point value where NaN != NaN
returns .TRUE. To check for NaNs, pass the same variable as both
arguments.
A compiler must assume that the two arguments are
not the same variable, and the test will not be optimized away.
Interprocedural or whole-program optimization may delete this
test. The ISNAN functions will be replaced by the correct
Fortran 03 intrinsic once the intrinsic is widely available.
Parameters:
DIN1
DIN1 is DOUBLE PRECISION
DIN2
DIN2 is DOUBLE PRECISION
Two numbers to compare for inequality.
