Returns the square root of the underflow and overflow thresholds if the exponent-range is very large.
call slabad( small, large )
call dlabad( small, large )
These routines are no-op and kept for compatibility reasons. They used to correct the overflow/underflow behavior of machines that are not IEEE-754–compliant.
REAL for slabad
DOUBLE PRECISION for dlabad.
The underflow threshold as computed by ?lamch.
REAL for slabad
DOUBLE PRECISION for dlabad.
The overflow threshold as computed by ?lamch.
On exit, if log10(large) is sufficiently large, the square root of small, otherwise unchanged.
