How many decimal digits of float - seven significant digits in detail - technical article
To better illustrate the floating point type, we use float, double and long double. Any difference? Double precision is twice the precision of floating-point numbers. The floating-point type is a 32-bit IEEE 754 single precision floating-point type 1-bit marker (8-bit refers to the value, 23 * refers to the scalar value), that is, the floating-point type has 7-bit decimal data precision. Double is a 64 bit IEEE 754 double precision floating-point type (1 bit for mark, 11 bits for exponent value, 52 * bits for value), that is, double has a precision of 15 decimal places. Let's take an example: for the quadratic
