Python log base 10 numpy
Return the base 10 logarithm of the input array, element-wise. Show Input values. outndarray, None, or tuple of ndarray and None, optionalA location into which the result is stored. If provided, it must have a shape that the inputs broadcast to. If not provided or None, a freshly-allocated array is returned. A tuple (possible only as a keyword argument) must have length equal to the number of outputs. wherearray_like, optionalThis condition is broadcast over the input. At locations where the condition is True, the out array will be set to the ufunc result. Elsewhere, the out array will retain its original value. Note that if an uninitialized out array is created via the default For other keyword-only arguments, see the ufunc docs. ReturnsyndarrayThe logarithm to the base 10 of x, element-wise. NaNs are returned where x is negative. This is a scalar if x is a scalar. Notes Logarithm is a multivalued function: for each x there is an infinite number of z such that 10**z = x. The convention is to return the z whose imaginary part lies in [-pi, pi]. For real-valued input data types, For complex-valued input, References 1M. Abramowitz and I.A.

The convention is to return the z whose imaginary part lies in (-pi, pi]. For real-valued input data types, For complex-valued input, In the cases where the input has a negative real part and a very small negative complex part (approaching 0), the result is so close to -pi that it evaluates to exactly -pi.

Parameters : array : [array_like]Input array or object.
How do you write log10 in Python?Description. The log10() method returns base-10 logarithm of x for x > 0.. Syntax. Following is the syntax for log10() method − import math math.log10( x ) ... . Parameters. x − This is a numeric expression.. Return Value. This method returns the base-10 logarithm of x for x > 0.. Example. ... . Output.. How do I write Numpy log in Python?log() in Python. The numpy. log() is a mathematical function that helps user to calculate Natural logarithm of x where x belongs to all the input array elements. Natural logarithm log is the inverse of the exp(), so that log(exp(x)) = x.
