Guys, i write a code for a program that have money on it, i am using

Match.ceil

feature for this, to predict they payment the buyer gonna use. The problem is for use

Match.ceil

i need to have the number in

float

, but then i read this https://stackoverflow.com/a/3730040 , which is telling that a bad one to use

float

for financial purpose. What i need to do? My code is something like this :

val a: Double = valueInput1.toDouble()
    val b: Double = 5000.toDouble()
    val c = Math.ceil(a/b)*5000
    println(c)

Are you writing this for the JVM?

Android precisely @Shawn

Did you read the SO answer?

sorry, but what is SO? StackOverflow? yes i read them

if at any point you call

.toDouble()

you lose the precision you would have with

BigDecimal

And i think i can to make it

BigDecimal

from the start, but AFAIK

Match.ceil

only can process

Double

😐

It’s

Math.ceil

okay i think im wrong in here, can you eli5 me Shawn?

To round a given BigDecimal to int like you would with

Math.ceil()

, you’d need something that looks kinda like this

val intValue = bigDecimal.setScale(0, RoundingMode.CEILING).intValueExact()

hmm, seems interesting, thanks @Shawn i gonna try this
