floating point - C: printf a float value

Question

I want to print a float value which has 2 integer digits and 6 decimal digits after the comma. If I just use printf("%f", myFloat) I'm getting a truncated value.

I don't know if this always happens in C, or it's just because I'm using C for microcontrollers (CCS to be exact), but at the reference it tells that %f get just that: a truncated float.

If my float is 44.556677, I'm printing out "44.55", only the first two decimal digits.

So the question is... how can I print my 6 digits (and just the six of them, just in case I'm having zeros after that or something)?

Answer 1

You can do it like this:

printf("%.6f", myFloat);

6 represents the number of digits after the decimal separator.
