Cmath log10
Web1. What is the time complexity of log10 function in cmath ? Its nowhere mentioned on the internet. Does anyone know for sure ? Later edit: My initial question was if the following code is faster. int numOfDigits (int n) { return (int)log10 (n) + 1; } than this. int numOfDigits (int n) { int count = 0; while (n) { count ++; n /= 10; } return 0; } Webcmath.isinf(x) Check whether x is a positive or negative infinty: cmath.isnan(x) Checks whether x is NaN (not a number) cmath.log(x[, base]) Returns the logarithm of x to the base: cmath.log10(x) Returns the base-10 logarithm of x: cmath.phase() Return the phase of a complex number: cmath.polar() Convert a complex number to polar coordinates ...

WebJun 30, 2024 · The cmath module provides two methods namely log() and log10() for logarithmic calculations on complex numbers. The log() function takes a complex number as first input and an optional argument representing the base of the logarithmic function. When we pass only the complex number as input to the log() function, it returns the natural log …
WebReturns a valarray containing the common logarithm (base-10 logarithm) of all the elements of x, in the same order. The function calls log10 (unqualified) once for each element. This function overloads cmath's log10. Parameters x valarray containing elements of a type for which the unary function log10 is defined. Return value A valarray object with the … WebThe cmath.log10() method in Python is used to compute the base-10 logarithm of a complex number. The method takes a single argument, which is the complex number whose base-10 logarithm is to be computed. The syntax for using cmath.log10() is as follows:
