VEX - converting ints and floats to strings

[SteveNi]

Hi

So basically I have a certain float value, lets say 3.68, and I want to get the digits before the comma (there are no functions that rounds to the lowest integer), so that I can later use that in some math operations.

I know I can use split() to split to the point, and sprintf() to convert to string, but I cant get this last function to work, for example if I wrote

float _x = sprintf("%g",3.68); 

But this gives me an error...

Anyone knows how to convert to string and back to the original variable type?

 

Thanks

I may be misunderstanding you, but I think what your looking for is floor().

I think  MrScienceOfficer give you what you are looking for.

BTW, to convert float to string and string to float, etc...:

itoa: https://www.sidefx.com/docs/houdini15.5/vex/functions/itoa

atoi: https://www.sidefx.com/docs/houdini15.5/vex/functions/atoi

atof: https://www.sidefx.com/docs/houdini15.5/vex/functions/atof

Awesome!!

I didnt know those functions...

 

Also I was searching for a function to round to the larger integer but I managed to do that by doing this thing on the number I need to round:

Example with 2.81:               2.81 + (1- (2.81%1))

Thanks a lot

to round to the larger int try ceil()
