Thread: what's wrong here?

Please, i cant find the mistake here:


char dec = "10.45";

float numb;

numb = (float)dec;

numb = numb/2;


i have the following message:

illegal operands 'double'/'int'

i have also tried

numb = numb/2.0

and its given:

illegal operands 'double'/'double'

so, if its wrong, how do i make mathematical operations between double-int, double-float, double-double???
