Loading, Is it possible to rotate a window 90 degrees if it has the same length and width? The floating-point number services offered by computers over the decades have varied greatly in format and behaviour, being in base ten, two, four, eight, or sixteen, and of various storage sizes, with various choices for precision and exponent range - for a fixed size, more precision means a smaller dynamic range and vice-versa. If the precision is omitted it defaults to 6 decimal places for 'e', 'E' and 'f' format types. Bushings are more efficient memory-wise. The option with 32 bits for both integers and floats is particularly attractive for small machines and embedded systems. 11.13. To learn more, see our tips on writing great answers.
