The case statement itself can manage full numeric check (for both integers and floating point numbers):
Quote:
#!/usr/bin/ksh
VAR=$1
if test "$VAR" = ""
then
echo empty
fi
case $VAR in
+([0-9])*(.)*([0-9]) )
echo it definitely is numeric
;;
* )
;;

Excel::Template::Container::Conditional(3pm) User Contributed Perl Documentation Excel::Template::Container::Conditional(3pm)
NAME
Excel::Template::Container::Conditional - Excel::Template::Container::Conditional
PURPOSE
To provide conditional execution of children nodes
NODE NAME
IF
INHERITANCE
CONTAINER
ATTRIBUTES
o NAME
This is the name of the parameter to test. It is resolved like any other parameter name. (q.v. VAR for more info.)
o VALUE
If VALUE is set, then a comparison operation is done. The value of NAME is compared to VALUE using the value of OP.
o OP
If VALUE is set, then this is checked. If it isn't present, then '==' (numeric equality) is assumed. OP must be one of Perl the numeric
comparison operators or the string comparison operators. All 6 of each kind is supported.
Note: If you want to use < or <=, you must instead use < or <=. This is to make sure it will parse with XML::Parser. You should
not need to use > or >= instead of > and >=, respectively.
o IS
If VALUE is not set, then IS is checked. IS is allowed to be either "TRUE" or "FALSE". The boolean value of NAME is checked against IS.
CHILDREN
None
EFFECTS
None
DEPENDENCIES
None
USAGE
<if name="__ODD__" is="false">
... Children here
</if>
In the above example, the children will be executed if the value of __ODD__ (which is set by the LOOP node) is false. So, for all even
iterations.
