Floating-point constant is too large for type 'type'
A value was assigned to a floating-point variable that is too large for the variables of this data type. See Integral Types Table for information about the range of values allowed in data types.
The following sample generates CS0594:
namespace x { public class a { public static void Main() { float f = 6.77777777777E400; // CS0594, value too large } } }
