Using this operator, the response table is as follows: As for a small example: int x 0 int y &x //y is pointing to x const char myText 'Text' You might however be interested in learning a bit more about what pointers are. Using this operator, the resulting truth table is as follows: 2 Answers Sorted by: 8 The (Asterisk) indicates the variable is a pointer. These are the basic boolean operators, often also referred to as logic gates.

= checks for a "greater than or equal to" relationship.Įxamples boolean result = 5<10 // result will be equal to trueīoolean result = 10<5 // result will be equal to false.

checks for a "greater than" relationship.

!= checks for a "not equal to" relationship.

= checks for an "equal to" relationship.

Returns A random number between min and max-1. max: upper bound of the random value, exclusive. Syntax random (max) random (min, max) Parameters min: lower bound of the random value, inclusive (optional). If the relationship that they check for is true, they return a 1. Description The random function generates pseudo-random numbers. These are the basic logic or comparison operators for arduinos and most other hardware and software. Int result = 7 % 5 // result assigned to value 2 Int result = 7 * 5 // result assigned to value 35 Math or CPU Registers: A and B Status Register: PSW (Program Status Word) Pointer Registers: DPTR (Data Pointer DPL, DPH) and SP (Stack Pointer) I/O Port.

Floating-point numbers are often used to approximate analog and continuous values because they have greater resolution than integers.

modulo or remainder operator, is indicated by a %.Įxamples int result = 7 + 5 // result assigned to value 12 Description Datatype for floating-point numbers, a number that has a decimal point.Arduino-Plus/hardware/tools/avr/avr/include/math.h. multiplication operator is indicated by a *. Write decimal numbers, hex numbers, temperature, clock digits, characters, and strings to the seven segment LED modules supported by the AceSegment library.
