Many hardware floating-point units use the IEEE 754 standard. Because, 65 is ASCII value of ‘a’. The IEEE Standard for Floating-Point Arithmetic is a technical standard for floating-point arithmetic established in 1985 by the Institute of Electrical and Electronics Engineers. It will convert a decimal number to its nearest single-precision and double-precision IEEE 754 binary floating-point number, using round-half-to-even rounding (the default IEEE rounding mode). With this converter you can convert a decimal number into a floating point number (IEEE 754) and vice versa. If the exponent has minimum value (all zero), special rules for denormalized values are followed. IEEE 754 binary representation. Bit 31 (the leftmost bit) show the sign of the number. The best result is usually the one closer to the value that was entered, so you should check for that. Some values are Floating points in the IEEE 754 Format (four bytes). The biggest problem, of course, is keeping track of the decimal point. The value of a IEEE-754 number is computed as: sign * 2 exponent * mantissa The sign is stored in bit 32.
