Simple expression question

[Tom]

I have simple expression, that returns floating value in Font sop in Text parameter. All I want to do, is to get value, that is only with two decimal numbers, behing point, not eight.

For example, i get 3.12345, but want to get only 3.12.

Searched for this in help, but I didnt find.

Thanks in advance,

Tom.

printf don't seem to exist in hscript for formatting floats but you could just do a simple expression as:

`round(3.12345*100)/100`

Not super pretty but gets the job done

[ben]

maybe :

trunc(3.123456*100)/100

edit : round works too to but watch out that it will actually... round.

round(19.999*100)/100 = 20

you might want to try python.

Change your expression language to python > Set Keyframe on first frame and use round function in Text parameter.

round(3.16159265,2)

3.16

Cheers!!

Ah my bad. just realized you are not really looking for this.

it may be over killing but string slicing will do the job.

a = 3.99999

b = str(a)

return b[0:4]

3.99
