| Examples |
double a; // Declare variable "a" of type float
a = 1.5387; // Assign "a" the value 1.5387
double b = -2.984; // Declare variable "b" and assign it the value -2.984
double c = a + b; // Declare variable "c" and assign it the sum of "a" and "b"
float f = (float)c; // Converts the value of "c" from a double to a float |
| Description |
Datatype for floating-point numbers larger than those that can be stored in a float. A float is a 32-bit values that can be as large as 3.40282347E+38 and as low as -3.40282347E+38. A double can be used similarly to a float, but can have a greater magnitude because it's a 64-bit number. Processing functions don't use this datatype, so while they work in the language, you'll usually have to convert to a float using the (float) syntax before passing into a function. |
