How do I make something that takes a percentage out of something?

pluto

ok so i know how to calculate percentage, but idk how to make it so like for example
take 10% of 100

person

var outcome = y % x;

pluto

person ok yeah but that apparently returns the remainder of a division problem

person

var y = prompt("divisor"); var x = prompt("dividend"); var outcome = y % x; textSize(24); text("when dividing " + (x + (" by " + y)), 100, 170); text("the outcome is" + outcome, 100, 200);

person

idk seems to work for me

pluto

what.

pluto

oh yeah what i meant is that- lemme just show you

var percentCalc = 100*1/cost; //turns out, it's just you're average whole number
var cost = 100;

if (bla bla bla) {
  cost  -= percentCalc //which arises here when the actual thing isnt a percent, instead a whole number
}

ackvonhuelio

pluto
wouldnt it just be
var onePercent = (totalCost/100); tenPercent = onePercent*10;

person

oh i see in that case get a calculator or something

pluto

person elaborate

Letti42

number * 0.1

Letti42

Letti42 or if you want it to be a specific percentage each time, it'd be:

var number = 100;
var percent = 10; //in percent, so this would be 10%
var newNumber = number * (percent/100)

pluto

Letti42 that's what i was just talking about, its kinda of a whole number and not an actual percentage
