In KiXtart, variables are always of one fundamental data type: Variant. The current implementation of KiXtart uses three types of variants: long integers, doubles (8-byte floating point numbers) and strings. A variant of type string can contain up to 32,000 characters. Integer variables can contain any value between ?2,147,483,648 and 2,147,483,647. The type of a variable is automatically changed to the result of the expression that is assigned to it. This means that if you assign a string to a variable containing an integer, the type of the variable is changed to a string.

code:

---

$a=25
$b=2
$c=$a/$b

---

code:

---

$a=25.0
$b=2.0
$c=$a/$b

---

Will result in "12.5" because $a and $b are both doubles, and the result of the math expression is a double.

Nice try, but no cigar

Real/floating point math Floating point expressions are now supported, and various supporting functions have been added: Round, CInt, CDbl, CStr and FormatNumber
