Why am I getting this error when trying to round a float

[nelmi]

So I’m trying to round a float using Ceil() (rounding upwards). But it gives me this error and I don’t know how to fix that, can someone help? Tia

Ceil[] is a failable function because it <decides> you have to call it using brackets.

Why is it failable ? I have really no clue, maybe if you ask it to Ceil() to the int limit it would fail ?

if(MyCeiledNumber := Ceil[MyNumber]):
    # do things

It’s because Inf, -Inf, and NaN are floats but not valid integers
