5.1 Type Conversion Functions
5.1.9 Word (signed), double word (signed) type → double-precision real type conversion
INT_TO_LREAL(_E), DINT_TO_LREAL(_E)
Operation Error
No operation error occurs in the execution of the INT_TO_LREAL(_E) and
DINT_TO_LREAL(_E) functions.
Program Example
(1) The program which converts word (signed) type data input to into double-precision real
type data, and outputs the operation result from .
(a) Function without EN/ENO (INT_TO_LREAL)
[Structured ladder]
[ST]
g_lreal1 := INT_TO_LREAL(g_int1);
(b) Function with EN/ENO (INT_TO_LREAL_E)
[Structured ladder]
[ST]
g_bool3 := INT_TO_LREAL_E(g_bool1, g_int1, g_lreal2);
(2) The program which converts double word (signed) type data input to into double-
precision real type data, and outputs the operation result from .
(a) Function without EN/ENO (DINT_TO_LREAL)
[Structured ladder]
[ST]
g_lreal1 := DINT_TO_LREAL(g_dint1);
