Round Float with decimal places[SOLVED]

[Alex W.]

Round Float with decimal places.

EXAMPLE:
Source Float: < 54.2486234 >
- Result Float with "None" decimal places: < 54 >
- Result Float with "One" decimal places: < 54.2 >
- Result Float with "Two" decimal places: < 54.24 >
- Result Float with "Three" decimal places: < 54.248 >
- Result Float with "Four" decimal places: < 54.2486 >

EDIT: Now you can store the result as a String!

Hi,

 Are you doing this to then save it as a string or else?

Hmm, good idea. I have edit the code.
Now you can store the result as String. See the first post.

Hi,

 Well Maybe then there is a more flexible way out of this.

either you can write an action implement this
http://www.csharp-examples.net/string-format-double/

which would expose a lot of power into how you want to format your float as a string.

or use an Action Maddox shared some time ago.

http://hutonggames.com/playmakerforum/index.php?topic=267.0

Be sure to check the reference provide in this thread to know all the different options available, including float rounding "##.##" and stuff like that.

That's really handy! Should be in the Ecosystem. The round float action that already exists is quite limited.

[jeanfabre]

Hi,

the ConvertFloatToString action shipped with PlayMaker does exactly that. Have you tried?

Bye,

Hi Jean,

No, it didn't occur to me that the action you mentioned would do the trick as well. Now I know for the future.
