Module

Math

Wraps the math functions and constants from Javascript's built-in Math object. See Math Reference at MDN.

#Radians 

type Radians = Number

An alias to make types in this module more explicit.

#abs 

abs :: Number -> Number

Returns the absolute value of the argument.

#acos 

acos :: Number -> Radians

Returns the inverse cosine of the argument.

#asin 

asin :: Number -> Radians

Returns the inverse sine of the argument.

#atan 

atan :: Number -> Radians

Returns the inverse tangent of the argument.

#atan2 

atan2 :: Number -> Number -> Radians

Four-quadrant tangent inverse. Given the arguments y and x, returns the inverse tangent of y / x, where the signs of both arguments are used to determine the sign of the result. If the first argument is negative, the result will be negative. The result is the angle between the positive x axis and a point (x, y).

#ceil 

ceil :: Number -> Number

Returns the smallest integer not smaller than the argument.

#cos 

cos :: Radians -> Number

Returns the cosine of the argument.

#exp 

exp :: Number -> Number

Returns e exponentiated to the power of the argument.

#floor 

floor :: Number -> Number

Returns the largest integer not larger than the argument.

#imul 

imul :: Int -> Int -> Int

Returns the result of the C-like 32-bit multiplication of the two arguments.

#log 

log :: Number -> Number

Returns the natural logarithm of a number.

#max 

max :: Number -> Number -> Number

Returns the largest of two numbers.

#min 

min :: Number -> Number -> Number

Returns the smallest of two numbers.

#pow 

pow :: Number -> Number -> Number

Return the first argument exponentiated to the power of the second argument.

#round 

round :: Number -> Number

Returns the integer closest to the argument.

#sin 

sin :: Radians -> Number

Returns the sine of the argument.

#sqrt 

sqrt :: Number -> Number

Returns the square root of the argument.

#tan 

tan :: Radians -> Number

Returns the tangent of the argument.

#trunc 

trunc :: Number -> Number

Truncates the decimal portion of a number. Equivalent to floor if the number is positive, and ceil if the number is negative.

#remainder 

remainder :: Number -> Number -> Number

Computes the remainder after division, wrapping Javascript's % operator.

#(%)

Operator alias for Math.remainder (left-associative / precedence 7)

#e 

e :: Number

The base of natural logarithms, e, around 2.71828.

#ln2 

ln2 :: Number

The natural logarithm of 2, around 0.6931.

#ln10 

ln10 :: Number

The natural logarithm of 10, around 2.3025.

#log2e 

log2e :: Number

The base 2 logarithm of e, around 1.4426.

#log10e 

log10e :: Number

Base 10 logarithm of e, around 0.43429.

#pi 

pi :: Number

The ratio of the circumference of a circle to its diameter, around 3.14159.

#tau 

tau :: Number

The ratio of the circumference of a circle to its radius, around 6.283185.

#sqrt1_2 

sqrt1_2 :: Number

The Square root of one half, around 0.707107.

#sqrt2 

sqrt2 :: Number

The square root of two, around 1.41421.
