Program code
DEF BOOL BOOL_ERG
DEF REAL REAL_ERG
DEF AXIS AXIS_ERG
BOOL_ERG=ISNUMBER("1234.9876Ex-7")

Variable for the result of the interrogation with ISNUMBER
Type: BOOL
Value: TRUE
FALSE
The AXNAME command converts the specified <string> into an axis
identifier.
Note:
If the <string> cannot be assigned a configured axis identifier, an
alarm is initiated.
Variable for the result of the type conversion with AXNAME
Type: AXIS
ISNUMBER supplies the value TRUE, if the
<string> represents a valid REAL number in
compliance with the language rules.
If ISNUMBER supplies the value FALSE, when
calling NUMBER with the same <string>, an
alarm is initiated.
