get string floating value in division

[JayPee]

Script Name: strDivide

Description: Allows you to divide two integers. It returns a floating value. Note: the floating value is in string datatype.

Version:

• 1.1 - added division of negative numbers and some variable cleanups
  

Parameters(should be in order):

• dividend - this should be a number not a string
  
• divisor - this should be a number not a string
  
• number of decimal digits.
  

Note: You must have this source modification http://rathena.org/board/topic/60307-additional-script-command-for-math-function-absx/page__pid__85826#entry85826. Since absolute script command is not yet added in rathena SVN.
