The JavaScript Number type is a double-precision 64-bit binary format IEEE 754 value, like double in Java or C#. This means it can represent fractional values, but there are some limits to what it can store.

JavaScript numbers are always stored as double precision floating point numbers, following the international IEEE 754 standard. This format stores numbers in 64 bits, where the number (the fraction) is stored in bits 0 to 51, the exponent in bits 52 to 62, and the sign in bit 63: If decimal part is greater than 0.5, then number is rounded to next integer which has greater absolute value. Absolute value refers to the magnitude value of the number regardless of its sign (for example 12 has greater absolute value than 11, -10 has greater absolute value than -9).
