Operands
The Double Integer to Real function converts a 32-bit,
signed integer (IN) into a 32-bit real number loads the
ENO
result into the variable specified by OUT.
OUT
Error conditions that set ENO = 0: SM4.3 (run-time),
0006 (indirect address)
224 226
Operands
The Real To Double Integer function converts a real
value (N) to a double Integer value and loads the result
ENO
into the variable specified by OUT.
OUT
Error conditions that set ENO = 0: SM1.1 (overflow),
SM4.3 (run-time), 0006 (indirect address)
