float() (cast)

Converts a value to the float data type. Here is an example (see the constants reference for an explanation of the “2.0f”):

int x = 2;
float f = float(x);  // f now holds 2.0f, a float value

The value x can be of any type. However, if x is not a number (like an int), you will get strange results.

See the float reference for details about the precision and limitations of float values on the Maple.
