9.9.2 BOOL_TO Conversions
Conversion from type BOOL to any other type:
For number types the result is 1, when the operand is TRUE, and 0, when the operand
is FALSE.
For the STRING type the result is ‚TRUE' or ‚FALSE'.
Examples in IL:
LD TRUE
BOOL_TO_INT
ST i (*Result is 1 *)
LD TRUE
BOOL_TO_STRING
ST str (*Result is 'TRUE' *)
LD TRUE
BOOL_TO_TIME
ST t (*Result is T#1ms *)
LD TRUE
BOOL_TO_TOD
ST (*Result is TOD#00:00:00.001 *)
LD FALSE
BOOL_TO_DATE
ST dat (*Result is D#1970-01-01 *)
LD TRUE
BOOL_TO_DT
ST dandt (*Result is DT#1970-01-01-
00:00:01 *)
Examples in ST:
i:=BOOL_TO_INT(TRUE); (* Result is 1 *)
str:=BOOL_TO_STRING(TRUE); (* Result is "TRUE" *)
t:=BOOL_TO_TIME(TRUE); (* Result is T#1ms *)
tof:=BOOL_TO_TOD(TRUE); (* Result is TOD#00:00:00.001*)
dat:=BOOL_TO_DATE(FALSE); (* Result is D#1970 *)
dandt:=BOOL_TO_DT(TRUE); (* Result is DT#1970-01-01-
00:00:01 *)
