How do I convert a float to FString?

I’m trying to print a debug message.

float f = 1.0f;
if (GEngine)
{
    GEngine->AddOnScreenDebugMessage( -1,1.0,FColor::Red, TEXT(f) );
}

Dear Pinheiro,

To convert float to Fstring you do this:

FString TheFloatStr = FString::SanitizeFloat(f);

To get the TCHAR version of this FString quickly you can do this

*TheFloatStr

so the final result is:

FString TheFloatStr = FString::SanitizeFloat(f);
GEngine->AddOnScreenDebugMessage( -1,1.0,FColor::Red, *TheFloatStr );

to convert FString to float I have tutorial on this here:

If this answers your question please mark the checkmark by my answer so others know it is resolved

That worked, thanks!

SanitizeFloat seems to expect >=0, is there another function who doesnt?

FString FString::SanitizeFloat( double InFloat )
{
// Avoids negative zero
if( InFloat == 0 )
{
InFloat = 0;
}

FString::Printf(TEXT("%f"),InFloat);
