问题 I'm looking for a method to convert the exact value of a floating-point number to a rational quotient of two integers, i.e. a / b , where b is not larger than a specified maximum denominator b_max . If satisfying the condition b <= b_max is impossible, then the result falls back to the best approximation which still satisfies the condition. Hold on. There are a lot of questions/answers here about the best rational approximation of a truncated real number which is represented as a floating

问题 I am working on a new model which is very sensitive to the interpolation/fit used to describe a certain dataset. I have some success with linear splines and logarithmic fits but I think there is still significant room for improvement. My supervisor suggested I take a look at exponential splines. I have found some books on the theory of exponential spines but no reference to a library or code example to follow. Is there a library that I am unaware of that supports this feature? 来源： https:/
