TO_** (Integer Conversion Group)
TO_** (Integer Conversion Group)
These instructions convert integers, bit strings, real numbers, and text strings to integers.
*1 The valid ranges depend on the data types of In and Out.
*2 If you omit the input parameter, the default value is not applied. A building error will occur.
These instructions convert the integer, bit string, real number, or text string in In to an integer.
The name of the instruction is determined by the data type of conversion result Out. For example, if Out
is the LINT data type, the instruction is TO_LINT.
The following example for the TO_LINT instruction is for when In is LREAL#1.0e+10.
