The number 20000001 = 0x1312d01 needs 25 bits to be represented exactly, so it must be rounded. The normal rounding mode for values exactly half-way between two representable values is rounding to last-bit-zero, hence 20000001 is rounded to 20000000 as a float.

Single-precision floating-point format (sometimes called FP32 or float32) is a computer number format, usually occupying 32 bits in computer memory; it represents a wide dynamic range of numeric values by using a floating radix point. A floating-point variable can represent a wider range of numbers than a fixed-point variable of the same bit width at the cost of precision. A signed 32-bit integer variable has a maximum value of 2 … In computing, floating-point arithmetic (FP) is arithmetic that represents real numbers approximately, using an integer with a fixed precision, called the significand, scaled by an integer exponent of a fixed base.
