![]() ![]() The largest value a number can hold is 2 1024 - 1 (with the exponent being 1023 and the mantissa being 0.1111… in base 2), which is obtainable via Number.MAX_VALUE. Therefore, the mantissa's precision is 2 -52 (obtainable via Number.EPSILON), or about 15 to 17 decimal places arithmetic above that level of precision is subject to rounding. The mantissa is stored with 52 bits, interpreted as digits after 1.… in a binary fractional number. ![]() Number = ( − 1 ) sign ⋅ ( 1 mantissa ) ⋅ 2 exponent \text Thinking about it as scientific notation: The exponent is the power of 2 that the mantissa should be multiplied by. The mantissa (also called significand) is the part of the number representing the actual value (significant digits). 52 bits for the mantissa (representing a number between 0 and 1).1 bit for the sign (positive or negative).Very briefly, an IEEE 754 double-precision number uses 64 bits to represent 3 parts: This means it can represent fractional values, but there are some limits to the stored number's magnitude and precision. The JavaScript Number type is a double-precision 64-bit binary format IEEE 754 value, like double in Java or C#.
