LET
(Statement)
Assign a value to a given variable.
[LET] <variablename> = <arithmetic expression>
This statement assigns the value of <arithmetic expression> on the right-hand side to the variable specified by <variablename> on the left-hand side.
[LET] can be omitted.
Basically, the data type of <variablename> and that of <arithmetic expression> must correspond. If not, this statement converts the data type with the following rules.
-
The data type of the assigned value is converted to that of <variablename>.In the type conversion from real to integer, the fractional part is rounded off.In the type conversion from double-precision variable of type real to single-precision one, the value is rounded to 7 significant digits.
-
Calculations are performed based on the type with the higher precision.
