Operators — Ze Documentation

Ze supports the standard set of arithmetic, comparison, and logical operators. Every operator has both a symbol form and one or more word forms in all three languages.

Arithmetic

Operation	Symbol	English word	Tagalog word	Bisaya word
Add	`+`	`plus`	`dagdag`	`dagdag`
Subtract	`-`	`minus`	`bawas`	`bawas`
Multiply	`*`	`times` / `multiply`	`beses`	`pilo`
Divide	`/`	`divide`	`hatiin`	`bahinon`
Modulo	`%`	`remainder` / `modulo`	`natira`	`nahibilin`
Power	`^`	`power` / `squared`	`puwersa`	`gahum`

show 10 + 3         # 13
show 10 minus 3     # 7
show 4 times 5      # 20
show 10 divide 4    # 2.5
show 10 remainder 3 # 1
show 2 ^ 8          # 256

Comparison

All comparison operators return true or false.

Meaning	Symbol	English phrase	Tagalog phrase	Bisaya phrase
Equal	`==`	`is` / `is equal to`	`ay` / `ay katumbas ng`	`mao` / `katumbas sa`
Not equal	`!=`	`is not` / `is not equal to`	`ay hindi`	`dili sama sa` / `dili katumbas sa`
Greater than	`>`	`is greater than`	`ay mas malaki sa`	`mas dako sa`
Less than	`<`	`is less than`	`ay mas maliit sa`	`mas gamay sa`
Greater than or equal	`>=`	`is at least` / `is greater than or equal`	`ay hindi bababa sa`	`dili moubos sa`
Less than or equal	`<=`	`is at most` / `is less than or equal`	`ay hindi lalampas sa`	`dili molapas sa`

show 5 is 5                         # true
show 5 is not 3                     # true
show 10 is greater than 7           # true
show 3 is less than 8               # true
show 5 is at least 5                # true  (>=)
show 4 is at most 10                # true  (<=)

# Tagalog
show 10 ay mas malaki sa 7          # true
show 5 ay hindi bababa sa 5         # true

# Bisaya
show 10 mas dako sa 7               # true
show 5 dili moubos sa 5             # true

Logical

Operator	English	Tagalog	Bisaya
AND	`and` / `and also`	`at` / `at saka`	`ug` / `ug usab`
OR	`or` / `or else`	`o` / `o kaya`	`o` / `o kaha`
NOT	`not`	`hindi`	`dili`

show true and false         # false
show true or false          # true
show not true               # false

# Tagalog
show totoo at mali          # false
show totoo o mali           # true
show hindi totoo            # false

# Bisaya
show tinuod ug bakak        # false
show tinuod o bakak         # true
show dili tinuod            # false

Precedence (highest to lowest)

Level	Operators
8 — Power	`^` / `power` / `puwersa` / `gahum`
7 — Multiply/Divide	`*` `/` `%` and word forms
6 — Add/Subtract	`+` `-` and word forms
5 — Comparison	`==` `!=` `<` `>` `<=` `>=` and phrase forms
3 — NOT	`not` / `hindi` / `dili`
2 — AND	`and` / `at` / `ug`
1 — OR	`or` / `o`

Use parentheses ( ) to override precedence:

show 2 + 3 * 4          # 14  (multiply first)
show (2 + 3) * 4        # 20  (parens first)

String Concatenation

The + operator concatenates strings. If either operand is not a string, it is automatically converted.

show "Hello, " + "World!"          # Hello, World!
show "Score: " + word(score)       # Score: 95
show "Items: " + count fruits      # Items: 3
