minecraft floating point arithmetic

a basic utiltiy pack to do math with floats and/or doubles

2 input functions

these functions all require the arguments {x:(number),y:(number)} and ouput the result to the storage gm:io out as well as returning the result as an int

gm:add

does x + y

gm:subtract

does x - y

gm:multiply

does x * y

gm:divide

this has 2 different sets of fuctionality

when specifying x as a number

does x / y

when specifying x as an array of numbers (will only divide up to the first 3 numbers in the array)

does [0] / y, [1] / y, [2] / y

outputs the resulting numbers in an array in the default output location and returns the length of the outputted array

gm:modulo

does x % y

implementation of fmod. fails if y is 0

gm:distance

gets the distance between x and y

for this operation 2 position arrays must be given instead of single values. If an array is empty or values are unspecified, the values will default to 0

gm:arctan2

does atan2(y, x)

this operation is similar to doing tan⁻¹(y/x), except that -180 ≤ atan2(y, x) ≤ 180. This gives a full 360° result, compared the 180° result of just doing tan⁻¹(y/x)

single input functions

these functions only requires {x:(number)} as an argument

gm:negate

does x * -1

gm:reciprocal

does 1 / x

gm:square

does x^2

gm:sqrt

does √x

gm:sin

does sin(x)

gm:cos

does cos(x)

gm:tan

does tan(x)

also outputs sin to storage gm._temp_:std var1 and cos to storage gm._temp_:std var2

gm:arcsin

does sin⁻¹(x)

-90 ≤ sin⁻¹(x) ≤ 90 where -1 ≤ x ≤ 1

gm:arccos

does cos⁻¹(x)

0 ≤ cos⁻¹(x) ≤ 180 where -1 ≤ x ≤ 1

gm:arctan

does tan⁻¹(x)

-90 ≤ tan⁻¹(x) ≤ 90

gm:round

does round(x)

Rounds x to the nearest integer. 0.5 will round up

gm:floor

does floor(x)

Rounds x down to the nearest integer

gm:ceil

does ceil(x)

Rounds x up to the nearest integer
