round - changeable?

[Superbeni]

Is it possible to change the numbers of a rounded number?
I would need a number rounded to one decimal number:
1.333333 -> 1.3
0.666666 -> 0.6

Is there any (easy) way to do this?

Code: Select all

integer=round(decimal);

I didn´t get it.
What should I write instead of decimal? or should I write decimal?
Integer is the variable?

Could you maybe write an example? (not a demo)

Sorry for this late answer, I didn´t had very much time.

Could anyone help, please?

Code: Select all

float roundNumber(float k, int places){
int i;
for(i=1; i<=places; i++){     //inflate the number
k*=10;
}
k=round(k);                       //round
for(i=1; i<=places; i++){     
k/=10;                               //deflate the number
}
return k;
}

Inflate, round, deflate.

A bit longer but I understood it.
thanks

Code: Select all

float roundNumber(float k, int places){
    int i;
    k*=pow(10, i);
    k=round(k);                       //round
   
    k/=pow(10,i);                               //deflate the number
    return k;
    }

Might be simpler.
