WebThe simplest way to distinguish between single- and double-precision computing is to look at how many bits represent the floating-point number. For single precision, 32 bits are used to represent the floating-point number. For double precision, 64 bits are used to represent the floating-point number. Take Euler’s number (e), for example.
