C float literal
Float constant
You could omit digits before the decimal point and specify a number as .5 instead of 0.5. A floating-point zero should be written as 0.0. The floating-point number may include an exponent specification of the form:e + exp. For example, 1.2e34 is a shorthand version of 1.2*1034.
float literal
The default type of a floating-point constant is double. You can append the suffix F or f to assign a constant the type float.
float f_var = 123.456F; // Initialize a float variable.Example - Scientific notation
Define float in In scientific notation (The E notation).
#include <stdio.h>
/*from w ww . j av a 2 s .co m*/
int main(){
float lightyear=5.878E12;
float jupiter=483400000;
float distance;
distance=jupiter/lightyear;
printf("Jupiter is %f light years from the sun.\n",distance);
return(0);
}
The code above generates the following result.
