toInt()

The toInt() function converts a string or double floating point to an integer. This is useful, for example, when you need to perform calculations on field values retrieved from the Message. Field values are retrieved as strings, and if you want to perform calculations on these values you must first convert the strings to either double floating point (see toDouble() below) or integers.

In both examples below, the value of $message.sum is "10".

Example 34

Using toInt() to convert a string value to an integer

Template

#set($a=$message.sum.toInt())

#set($b=$a+10)

$b

Output

20

 

Example 35

Not using toInt() – strings are concatenated

Template

#set($a=$message.sum)

#set($b=$a+10)

$b

Output

1010

 

The toInt() function can also be used to convert a boolean true/false to 0/1.

Example 36

Using toInt() to convert booleans to integers

Template

#set($bool_1=true)

#set($bool_2=false)

$bool_1

$bool_1.toInt()

$bool_2

$bool_2.toInt()

Output

true

1

false

0
