Normal Variable Manipulation
String Variable Manipulation
Normal Variable Manipulation
Basic Numeric Manipulation
| Symbol | Name | Example of Use |
| + | Add | Variable a+Variable b |
| - | Subtract | Variable a-Variable b |
| * | Multiply | Variable a*Variable b |
| / | Divide | Variable a/Variable b |
| ( | Bracket Open | |
| ) | Bracket Close | |
| ++ | Increment (Increase by one) | Variable a++ |
| -- | Decrement (Decrease by one) | Variable a-- |
Advanced Numeric Manipulation
| sqrt(Variable) | Square Root | |
| pow(Variable a,Variable b) | To the Power of | Variable a to the power of Variable b |
Logical Manipulation
| Variable a AND Variable b | AND |
| |||||||||||||||
| Variable a OR Variable b | OR |
| |||||||||||||||
| NOT Variable a | NOT |
| |||||||||||||||
| Variable a XOR Variable b | XOR |
|
Precedence
| 1 [Done First] | () | ||
| 2 | ++ | -- | |
| 3 | * | / | % |
| 4 | + | - | |
| 5 | NOT | ||
| 6 | AND | ||
| 7 [Done Last] | OR |
String Variable Manipulation
Whole String Manipulation
| UPPER(String a) | Change all Characters in String a to upper case(Character Strings) |
| LOWER(String a) | Change all Characters in String a to lower case(Character Strings) |
Selective String Manipulation
| substr(String a,Variable a,Variable b) | A string is created from String a starting at Variable a number of characters in, and Variable b characters long. |
