Math Bundle

The Math Bundle offers useful mathematical functions and constants. It consists of 4 modules:

1. Math Constants

This module offers regularly needed mathematical constants. You can select the constant via the dropdown menu by clicking on the constant name. They are exact to 100 decimal places, which should be enough for most cases.

Selectable constants are:

pi: Well, pi (or half the circumference of a circle with radius 1)

pi/4: pi over 4 (or 1/8 the circumference of a circle with radius 1)

pi/2 pi over 2 (or 1/4 the circumference of a circle with radius 1)

3pi/4: 3 times pi over 4 (or 3/8 the circumference of a circle with radius 1)

2pi: 2 times pi (or the circumference of a circle with radius 1)

1/pi: 1 over pi

1/2pi: 1 over (2 times pi)

e: Euler's Number

sqrt(2): Square root of 2

1/sqrt(2): 1 over square root of 2

log(2): Natural logarithm of 2 (aka. ln(2))

2. 1-Op Math

This module offers 1-operand math functions. You can select the function via the dropdown menu by clicking on the function name.

Selectable functions are:

abs: Absolute value

ceil: Round to the next larger integer

floor Round to next smaller integer

exp: Exponential function (e to the power of the input)

log: Natural logarithm (aka. ln)

log10: Logarithm to base 10

round: Round to the nearest integer

sign: Signum function. Output is 1 if input > 0, 0 if input = 0, -1 if input < 0

sqrt: Square root

1/x: Reciprocal value

3. 2-Op Math

This module offers 2-operand math functions. You can select the function via the dropdown menu by clicking on the function name.

Selectable functions are:

add: Add input values (a+b)

sub: Subtract input values (a-b)

mul Multiply input values (a*b)

div: Divide input values (a/b). If input b = 0, the output is NaN

mod: Modulo operator (a%b). If input b = 0, the output is NaN (Wikipedia)

pow:Power function (a^b)

log: Logarithm function, where b is the base (log_b(a))

atan2: 2-argument arctangent (Wikipedia)

hypot: Length of the hypotenuse (sqrt(a^2 + b^2))

min: Return the minimum of a and b

max: Return the maximum of a and b

4. Trig Math

This module offers trigonometric functions. You can select the function via the dropdown menu by clicking on the function name.

Selectable functions are:

sin: Sine

cos: Cosine

tan: Tangent

asin: Arcus sine (inverse sine)

acos: Arcus cosine (invere cosine)

atan: Arcus tangent (inverse tangent)

sinh: Hyperbolic sine

cosh: Hyperbolic cosine

tanh: Hyperbolic tangent

IMPORTANT: Functions are evaluated from top to bottom, so if you want to use the result of function A in function B, function A has to be above function B.
