[Solved] Math (real rounded upward)

[best_player_88]

Math (real rounded upward) -> is there a base function to do it?

 

[rulerofiron99]

Set Decimals = RealNum - Integer(RealNum)
If Decimals > 0.5 then
set RealNum = Integer(RealNum) + 1
else
set RealNum = Integer(RealNum)

You could just skip all that hassle and use:

• Set integerVariable = (Integer((realVariable + 0.50)))

 

[rulerofiron99]

^ much better

 

[best_player_88]

Set Decimals = RealNum - Integer(RealNum)
If Decimals > 0.5 then
set RealNum = Integer(RealNum) + 1
else
set RealNum = Integer(RealNum)

Decimals is not a function, I used that way also, my main quesion was if there was based function to make it use less functions.
nice try though

• set integervariable = (integer((realvariable + 0.50)))

Edit:
approved, but it will work only if you use 0.99 and not 0.5:

Real =0.99, need to bring it to int upward
0.99 + 0.99 =1.98 (int 1)
Real =0.01, need to bring it to int upward
0.01 + 0.99 = 1.00 (int 1)

set integervariable = (integer((realvariable + 0.99)))

4 commends became one!!!

Yeah, true.
By default, wc3 floors the real numbers when converting to integers.
Adding 0.50 to the real will change it into a rounding function.
Adding 0.99 to the real will change it into a ceiling function.

 

[edo494]

set myvar = I2R(R2I(myvar+0.5))

that should do it

Decimals is a variable representing the remainder of the number after its integer has been chopped off.

 

[Dr Super Good]

Adding 0.99 to the real will change it into a ceiling function.

Incorrect, it will convert 0.001 wrongly.

 

[Kitabatake]

Incorrect, it will convert 0.001 wrongly.

Yeah but it is practical.

Sure you could just go all:

If (realVar mod 1) not equal to 0, then intVar = integer(realVar+1), else intVar = integer(realVar)
​

If you really need it to be that accurate.

there is "integer" and "real", decimal not exist.

English is not my mother tounge, my intention was "ceilling function" and in most less commmends possible.

Yeah but it is practical.

If (realVar mod 1) not equal to 0, then intVar = integer(realVar+1), else intVar = integer(realVar)

Probably the best way to do it when you are facing reals who can become more precise than 0.01.
