Lua Math Floor

The function uses a perlin noise algorithm to assign fixed values to coordinates.

Lua math floor.

Here is an alternative implementation. Math floor x returns the largest integer smaller than or equal to x. To get an integer result during a division. Math randomseed 1234 math random math random math random.

Math ceil x returns the smallest integer larger than or equal to x. Math floor null returns 0 not a nan. In other case lua casts upperinto an integer sometimes giving math floor upper and others math ceil upper with unexpected results the same for lower. The following function rounds a number to the given number of decimal places.

Equal seeds produce equal sequences of numbers. The math randomseed function sets a seedfor the pseudo random generator. Because floor is a static method of math you always use it as math floor rather than as a method of a math object you created math is not a constructor. Math cos x returns the cosine of x assumed to be in radians.

The floor method rounds a number downwards to the nearest integer and returns the result. Lua math library we often need math operations in scientific and engineering calculations and we can avail this using the standard lua library math. Number math noise number x number y 0 number z 0. Function round num numdecimalplaces local mult 10 numdecimalplaces or 0 return math floor num mult 0 5 mult end.

Math cosh x returns the hyperbolic cosine of x. Use function div a b return a a b b end. Math deg x returns the angle x given in radians in degrees. If the passed argument is an integer the value will not be rounded.

Math exp x returns the value e power x. If you leave arguments out they will be interpreted as zero so math noise 1 158 is equivalent to math noise 1 158 0 0 and math noise 1 158 5 723 is equivalent to math noise 1 158 5 723 0.
