“A constant holding a Not-a-Number (NaN) value of type float. It is equivalent to the value returned by Float.intBitsToFloat(0x7fc00000).” We don’t have this type of constants for other numeric data types in Java. 3. Comparisons withNaN While writing methods in Java, we should chec...
There is NaN in most programming languages because they follow the standard. But not all the operations listed above return NaN in those languages. Some may throw exceptions if the language developers have decided so. Otherwise, NaN is usually used. For instance, you can not divide by zero in...
The NumPy nanmax() function computes the maximum value of an array, ignoring any NaN (Not a Number) values. If all values in the array or along the specified axis are NaN, a RuntimeWarning is raised and the result will be NaN.
The IEEE 754 standard dictates how floating point numbers work. I’ve talked aboutIEEE exceptions in C++before. This post is the Python counterpart. Python’s floating point types are implemented in terms of C’sdoubletype and so theC++ notesdescribe what’s going on at a low level. However...
