18 paź 2023 · Often you’ll need to round decimal numbers to their nearest integer values. Lua gives us the functions math.ceil and math.floor to do just that: -- Round up a number print (math.ceil (4.1)) -- This will output 5 -- Round down a number print (math.floor (4.9)) -- This will output 4.
The math library comprises a standard set of mathematical functions, such as trigonometric functions (sin, cos, tan, asin, acos, etc.), exponentiation and logarithms (exp, log, log10), rounding functions (floor, ceil), max, min, plus a variable pi.
Functions with the annotation " integer/float " give integer results for integer arguments and float results for non-integer arguments. The rounding functions math.ceil, math.floor, and math.modf return an integer when the result fits in the range of an integer, or a float otherwise.
5 gru 2021 · In other case Lua casts upper into an integer, sometimes giving math.floor(upper) and others math.ceil(upper), with unexpected results (the same for lower). The math.randomseed() function sets a seed for the pseudo-random generator: Equal seeds produce equal sequences of numbers.
