How many bytes is a float
WebApr 8, 2024 · 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 the stored number's magnitude and precision. Very briefly, an IEEE 754 double-precision number uses 64 bits to represent 3 parts: WebMar 16, 2024 · This returns 24 bytes in your case (and probably for most other people as well). In the case of CPython (the most common Python implementation), every float object will contain a reference counter and a pointer to the type (a pointer to the float class), which will each be 8 bytes for 64bit CPython or 4 bytes each for 32bit CPython.
