  Function definition: (Copy & paste into FileMaker's Edit Custom Function window)

If ( (x = 0) or (y = 0); 0; BitAnd( Div(x;2); Div(y;2) ) * 2 + If ( Mod(x;2) =1 and Mod(y;2) = 1; 1; 0 ) ) Click to copy

The TextStyleAdd() and TextColor() functions use numerical bitmasks as there arguments, for simple operations, + can be used to combine them.

For more complex operations, BitAnd() can be helpful, its output is only those bits set in both inputs:
BitAnd( Bold + Italic, Italic + Underline ) = Italic
