Round up number

[Pheaktra Capo]

Hello everybody.
I want to round up some number. For example:
1.2389 to 1.24 (2 decimal)
1.2389 to 1.239 (3 decimal)

I use DoubleToString(variable,2) and it just cut out the number, not round up the number.
Please help. Thanks in advance and have a nice day . . . .

MathFloor() rounds the number to the nearest integer below. We can use it together with some basic maths:

(MathFloor(1.2389*100)+1)/100 = 1.24

(MathFloor(1.2389*1000)+1)/1000 = 1.239

edit: oh, its probably bit easier with https://www.mql5.com/en/docs/math/mathceil
