// A float literal has a decimal point. When performing math
// A float literal doesn't need a decimal point. When performing math
// operations with numeric literals, ensure the types match. Zig
// does not perform unsafe type coercions behind your back:
//
// fn foo(bar: u16) f16 { return 13.5 * bar; } // ERROR!
// var foo: f16 = 13.5 * @as(u8, 5); // ERROR!
// var foo: f16 = 13.5 * 5; // This is a safe compile-time
// // conversion, so no problem!
// var foo: f16 = 13.5 * 5.0; // No problem, both are floats
// var foo: f16 = 5; // NO ERROR
// var foo: f16 = @as(u16, 5); // ERROR
//
// Please fix the two float problems with this program and
// display the result as a whole number.
