javascriptfloating-pointnumericaldouble-precision

Does JavaScript have double floating point number precision?

I know it's an odd question, but does JavaScript have the capacity to work with double's as opposed to single floats? (64 bit floats vs. 32 bits.)

Solution

  • All numbers in JavaScript are 64-bit floating point numbers.
