Description:
The Trunc function truncates a real-type value to an integer-type value. X is a real-type expression. Trunc returns an Int64 value that is the value of X rounded toward zero.
If the truncated value of X is not within the Int64 range, an EInvalidOp
exception is raised.
Delphi-Quellcode:
...
label51.caption := sectostr(Trunc(irig));
