Lua Math Floor

Number math noise number x number y 0 number z 0.

Lua math floor. Math cos x returns the cosine of x assumed to be in radians. Math deg x returns the angle x given in radians in degrees. Lua math library we often need math operations in scientific and engineering calculations and we can avail this using the standard lua library math. Math ceil x returns the smallest integer larger than or equal to x.

Math floor x returns the largest integer smaller than or equal to x. The function uses a perlin noise algorithm to assign fixed values to coordinates. Function round num numdecimalplaces local mult 10 numdecimalplaces or 0 return math floor num mult 0 5 mult end. Math randomseed 1234 math random math random math random.

Here is an alternative implementation. Math floor null returns 0 not a nan. To get an integer result during a division. Math floor x returns the largest integer smaller than or equal to x.

Math cosh x returns the hyperbolic cosine of x. The math randomseed function sets a seedfor the pseudo random generator. Math exp x returns the value e power x. Use function div a b return a a b b end.

If the passed argument is an integer the value will not be rounded. 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. 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. The following function rounds a number to the given number of decimal places.

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. Equal seeds produce equal sequences of numbers.
