a.k. from thus spake a.k.
As well as required arithmetic operations, such as addition, subtraction, multiplication and division, the IEEE 754 floating point standard has a number of recommended functions. For example
One recommended function that JavaScript does not provide, and which I should like to add to the
finite
determines whether its argument is neither infinite nor NaN and isnan
determines whether its argument is NaN; behaviours that shouldn't be particularly surprising since they're more or less equivalent to JavaScript's isFinite
and isNaN
functions respectively.One recommended function that JavaScript does not provide, and which I should like to add to the
ak
library, is nextafter
which returns the first representable floating point number after its first argument in the direction towards its second.
