Numbers
These puzzles provide means for various operations with numbers in your scenario.

"number"
This universally used puzzle provides the means to supply some number to your Puzzles scenario.

Numbers can be written without decimals (integers) or with decimals (floating-point numbers). Extra large or extra small numbers can be written with scientific (exponent) notation.

"angle"
This puzzle allows you to visually define angle (in degrees).

"arithmetic operation (with two inputs)"
This puzzle allows you to perform elementary arithmetic operations: addition (+), subtraction (-), multiplication (×) and division (÷), as well as exponentiation (^).

Please note that floating-point arithmetic is not always 100% accurate, and may produce unpredictable results when comparing numeric values. To get rid of those precision issues, you may use rounding with precision.

"arithmetic operation (with single input)"
This puzzle allows you to perform the following mathematical operations: square root (√), absolute value aka modulus (|x|), sign change aka negation (-), natural logarithm (ln), decimal logarithm (log10), natural exponential function (e^), and power of ten (10^).

Examples:

Please note that floating-point arithmetic is not always 100% accurate, and may produce unpredictable results when comparing numeric values. To get rid of those precision issues, you may use rounding with precision.
"round (to integer)"
This puzzle rounds a specified number. The *round* variant rounds a number to the nearest integer: 2.49 will be rounded down (producing 2), and 2.5 will be rounded up (producing 3). The *round up* variant rounds a number upward to the nearest integer: 2.1 will be rounded up (producing 3). The *round down* variant rounds a number downward to the nearest integer: 2.9 will be rounded down (producing 2).

Examples:

"round with precision"
This puzzle rounds a given number using the specified precision.

Examples:

Floating-point arithmetic is not always 100% accurate, and may produce unpredictable results when comparing numeric values. To get rid of those precision issues, you may use rounding with precision as follows:

"check"
This puzzle checks whether a specified number is even, odd, prime, whole, positive, negative, or divisible by some other number. The result is *true* if this is the case and *false* if not. For using with Logic puzzles.

Examples:

"clamp"
This puzzle constraints a number to be between the specified limits (inclusive).

Examples:

"random integer"
This puzzle returns a random integer number between specified numbers (inclusive both limits).

Note: supplying non-integer limits is possible, although this extends the range as this puzzle performs some additional rounding under the hood.
Examples:

"random fraction"
This puzzle returns a random floating-point number between 0 (inclusive) and 1 (exclusive).

In the following example this puzzle is used to generate a random color for a material:

"remainder"
This puzzle finds the remainder after division of one number by another (aka the modulo operation).

Examples:

"operations on list"
Performs an operation on the numbers of a specified list.

- *sum* - calculates the sum of all numbers in the list.
- *min* - finds the smallest number.
- *max* - finds the largest number.
- *average* - finds the arithmetic mean (as the sum of all numbers divided by the length of the list).
- *median* - finds the median (as the middle number when all numbers are sorted from smallest to largest).
- *modes* - finds the modes (as a list of numbers that appear the most frequently in the list).
- *standard deviation* - calculates the standard deviation (as the square root of the average of the squared deviations from the arithmetic mean).
- *random item* - returns a randomly chosen item.
Examples:

"trigonometric functions"
This puzzle allows you to calculate the values of the trigonometric functions *sine* (sin), *cosine* (cos), and *tangent* (tan), as well as the values of their inverse counterparts *arcsine* (asin), *arccosine* (acos), and *arctangent* (atan). The puzzle expects (or returns) values expressed in degrees.

Examples:

Please note that floating-point arithmetic is not always 100% accurate, and may produce unpredictable results when comparing numeric values. To get rid of those precision issues, you may use rounding with precision.
"constants"
This puzzle returns the following mathematical constants: pi (π), Euler's number e, the golden ratio (φ), square root of 2, square root of ½, and infinity value (∞).

Examples:
