SCULIB_DECODE_ANGLE

convert angle string to double precision angle

Description:

This routine converts an angle in dd:mm:ss.dd format into a double precision number in radians. It assumes that the input string specifies the angle in degrees. The process involves removing the ’:’ delimiters, then calling SLA_DAFIN to perform the conversion. An error will be returned if there are less than 2 ’:’ delimiters in the string, or if the SLA routine errors.

Invocation

CALL SCULIB_DECODE_ANGLE (STRING, ANGLE, STATUS)

Arguments

STRING = CHARACTER() (Given)
angle in xx:mm:ss.ddd format
ANGLE = DOUBLE PRECISION (Returned)
angle in radians
STATUS = INTEGER (Given and returned)
Global status
