Floating-Point Literal Loss of Precision Error

The compiler reports as error stating that your assignment of a floating-point literal to a variable of type float might result in a loss of precision.

When you assign a floating-point literal to a float variable, you must explicitly specify the type suffix. When you omit the suffix, the compiler assumes that the literal is of type double, which cannot be assigned to a float without an explicit cast. The following two statements illustrate a correct and an incorrect assignment statement:

float myFirstFloat = 1.0;   // compiler error
float mySecondFloat = 2.0F; // correct
