math ceiling/floor, round? [RESOLVED]

[The Good King]

how do you use these functions in RGSS?

I know RGSS defaultly uses math.floor (always rounds down; aka INT() ), but how do you math.floor and common rounding? (5-9, round up, 0-4, round down)

If I am not mistaken, Math.round(Number)

hmmm, ya i saw that l8r when i checked the help contents, but do you use Math w/o it giving you that "method 'Math' not defnined" error?

From the float object call round.

Like:

a = 4.5
p a.round # prints 5
a = 4.49
p a.round # prints 4

# Take this number as an example
num1 = 4.2
num2 = 4.55
num3 = 4.92

# Just takes out the decimal part. Same as Truncate, i guess
num1.to_i # ==> 4
num2.to_i # ==> 4
num3.to_i # ==> 4
num1.truncate # ==> 4
num2.truncate # ==> 4
num3.truncate # ==> 4

# Returns the smallest integer equal to or greater than the number
num1.ceil # ==> 5
num2.ceil # ==> 5
num3.ceil # ==> 5

# Returns the largest integer that does not exceed the number
num1.floor # ==> 4
num2.floor # ==> 4
num3.floor # ==> 4

#Returns the integer closest to the number
num1.round # ==> 4
num2.round # ==> 5
num3.round # ==> 5

# Returns the absolute value of the mumber (probably 'self')
num1.abs # ==> 4.2
num2.abs # ==> 4.55
num3.abs # ==> 4.92

That´s pretty much the relevant commands to transform a float into an integer. There´re other ways, implicitly or explicitly in code.

Bah that's what i get from using my own module and playing with C# form a long time XD

number.round is what I meant, the module I made was like Maths.round(number,decimals)
C# like

ya thx yall i got it
