SLA_DD2TF

Days to Hour,Min,Sec

ACTION:

Convert an interval in days into hours, minutes, seconds (double precision).

CALL:

CALL sla_DD2TF (NDP, DAYS, SIGN, IHMSF)

GIVEN:

RETURNED:

NOTES:

(1)

NDP less than zero is interpreted as zero.

(2)

The largest useful value for NDP is determined by the size of DAYS, the format of DOUBLE PRECISION floating-point numbers on the target machine, and the risk of overflowing IHMSF(4). On some architectures, for DAYS up to 1D0, the available floating-point precision corresponds roughly to NDP=12. However, the practical limit is NDP=9, set by the capacity of a typical 32-bit IHMSF(4).

(3)

The absolute value of DAYS may exceed 1D0. In cases where it does not, it is up to the caller to test for and handle the case where DAYS is very nearly 1D0 and rounds up to 24 hours, by testing for IHMSF(1)=24 and setting IHMSF(1-4) to zero.
