Parentheses are allowed in damage formulas and behaves similarly in modifying the order of operations. The modulo operator returns the value of the remainder rather than quotient.

You likely practiced division by doing long division with remainders.ġ50 mod 11 outputs the remainder (7) rather than the quotient (13). If you're still unclear on modulo, recall first learning about division. In other words, a single modulo operator is equivalent to using three arithmetic operations with two operands. Modulo operations use the "%" sign or percent sign. Thus, 3 ² in Ruby becomes: 3 ** 2 # => 9 Modulo/Modulus (%) Correspondingly, dividing by 0 in Ruby will throw in an error.Įxponents are defined with double asterisks "**". Producing a quotient with significant digits requires that at least one of the operands is a float.Īs explored in any pre-algebra class, dividing by 0 results as "undefined".
In this case, it is 1.ĭivision with Integer and Float Operands 3 / 2.0 # => 1.5 Since quotient in this example does not normally result as an integer, it is rounded down to the nearest integer. However, the quotient of two integer operands will always be an integer.
"3 divided by 2" should result in a value less than 2 and more than 1. The quotient's data type differs depending on the data types of the operands.ĭivision with Integer Operands 3 / 2 # => 1 The "\" or "back slash" is not interchangeable with the "forward slash" sign. The product of integers and floats will always be a float.ĭivision uses forward slash "/". The difference of integers and floats will always be a float. The sum of integers and floats will always be a float. Spaces are recommended between any operands (i.e. The order of operations for mathmatical calculations are implied in all cases. The four basic arithmetic operators should be self-explanatory, but are explained with Ruby syntax rules in mind. If a value is less than 1.0, then place one 0 before the dot. Ruby does not allow floating literals with no value before the dot. Negative floats are preceded by the negative sign with no space between the sign and the numerical value. Unless you actually want to use octal values, avoid using leading zeroes.įloating point values ( float for short) are values with any number of significant figures. Instead, values that start with "0" are treated as octal values. Numerical values that precede with "0" are not integers. In other words, what you see is what you get (in base 10). Negative integers are preceded by the negative sign with no space between the sign and the numerical value. Integers are whole number values with no significant figures. In order to make examples in this guide clear, the output will be explicitly stated within an associated comment on the same line.Īgain, comments are not meant to be explicitly typed in the formula box. But when creating your damage formula, the output is implied. Imagine that you're using a simple calculator and you input the following: Comments are preceded by the "#" symbol and are not meant to be explicitly typed in the formula box. However, the purpose of this guide is to introduce basic Ruby syntax and concepts so that you can make the most out the "Formula" field.Įxamples will include a Ruby statement and their outputs in the associated "comment". You do not need any prior programming experience in order to make your own formulas. Formulas must adhere to Ruby syntax rules even though this requirement isn't explicitly stated. RPG Maker VX Ace lets developers create their own custom damage formula for each Item and Skill in their database. 4.4.2 Division with Integer and Float Operands.
