Implicit type conversion

Function
During value assignments and parameter transfers, variables of different data types are
assigned or transferred.
The implicit type conversion triggers an internal type conversion of values.
Possible type conversions
from
REAL
INT
BOOL

10-10
Integer for whole values with prefix signs
Real for rational counting
Boolean TRUE and FALSE
ASCII character
Character string with alpha-numerical characters
Axis addresses and spindles
Coordinate transformations

At type conversion from REAL to INT, fractional values that are >=0.5 are rounded
up, others are rounded down (cf. ROUND function).
An alarm is output if values are exceeded.
Value <> 0 is equivalent to TRUE; value == 0 is equivalent to FALSE
