int to float
PostPosted: Thu Jul 12, 2012 10:14 am     Reply with quote
How can I make a float number from to integer:

float val;
int val1=12, val2=3;

I would like to make: val=12.3

Hi

Maybe this...

Code:
void mfloat(void){
float val;
int val1=12, val2=3;
val=val1+(float)val2/10;
printf("%3.1f\r\n",val);
}

Well if you want a floating point result, there has to be floating point maths 'somewhere'.
Remember there is actually no need to go 'float' at all though (vastly quicker).
Code:

void dfloat(void){
   int16 val;
   int val1=12, val2=3;
   val=((int16)val1*10)+val2;
   printf("%4.1w\r\n",val);
}


Generates the integer 123, and then displays this as 12.3.

Best Wishes
