|[tan() ](https://www.arduino.cc/reference/en/language/functions/trigonometry/tan/)| Calculates the tangent of an angle (in radians). The result will be between negative infinity and infinity. |
|[random() ](https://www.arduino.cc/reference/en/language/functions/random-numbers/random/)| The random function generates pseudo-random numbers. |
|[randomSeed() ](https://www.arduino.cc/reference/en/language/functions/random-numbers/randomseed/)| randomSeed() initializes the pseudo-random number generator, causing it to start at an arbitrary point in its random sequence. This sequence, while very long, and random, is always the same. |

|[bit()]( https://www.arduino.cc/reference/en/language/functions/bits-and-bytes/bit/)| Computes the value of the specified bit (bit 0 is 1, bit 1 is 2, bit 2 is 4, etc.). |
|[bitClear()]( https://www.arduino.cc/reference/en/language/functions/bits-and-bytes/bitclear/)| Clears (writes a 0 to) a bit of a numeric variable. |
|[bitRead()]( https://www.arduino.cc/reference/en/language/functions/bits-and-bytes/bitread/)|Reads a bit of a variable, e.g. bool, int. Note that float & double are not supported. You can read the bit of variables up to an unsigned long long (64 bits / 8 bytes). |
|[bitSet()]( https://www.arduino.cc/reference/en/language/functions/bits-and-bytes/bitset/)| Sets (writes a 1 to) a bit of a numeric variable. |
|[bitWrite()]( https://www.arduino.cc/reference/en/language/functions/bits-and-bytes/bitwrite/)| Writes to a bit of a variable, e.g. bool, int, long. Note that float & double are not supported. You can write to a bit of variables up to an unsigned long (32 bits / 8 bytes). |
|[highByte() ](https://www.arduino.cc/reference/en/language/functions/bits-and-bytes/highbyte/)| Extracts the high-order (leftmost) byte of a word (or the second lowest byte of a larger data type). |
|[lowByte()](https://www.arduino.cc/reference/en/language/functions/bits-and-bytes/lowbyte/)| Extracts the low-order (rightmost) byte of a variable (e.g. a word). |
