ceil: Take greater than or equal to the smallest integer x, if x is an integer, x is returned copysign: y is applied to the front of the sign of x, can be used 0 COS: find the cosine of x, x must be in radians degrees: the converted from radians to degrees x e: represents a constant exp: returns math.e, i.e. 2.71828 power of x expm1: returns the value of Math.E x (a value of 2.71828) th power minus. 1 FABS: returns x the absolute value of the factorial: take the value of x factorial floor: taking the maximum integer value less than or equal to x if x is an integer, it returns itself fmod: obtain a remainder of x / y, which is a floating point value frexp: returns a tuple (m, e), which is calculated as: x 0.5 and 1, respectively, except, to give a range of values of fsum: each element of the iterator, summing operation gcd: returns the greatest common divisor of x and y hypot: If x is not infinite in number, the return True, otherwise False isFinite: If x is positive infinity or negative infinity, then return True, otherwise False isinf: If x is positive infinity or negative infinity, True is returned, otherwise return False isNaN: if x is not numeric True, otherwise False ldexp: return x * (2 ** i) Value log: returns the natural logarithm of x, the default base e, base parameters given time, the number x of the given return Base, calculated as: log (x) / log ( base) log10: Returns x base 10 logarithm log1p: return x + NATURAL 1 value of the log (base e) of log2: Returns the group of x 2 log modf: returns a fractional part and an integer part of x composition tuples pi: numeric constants, pi pow: returns x to the power y, i.e. y ** x radians: the angle x is converted to radians sin: find x (x in radians) sine sqrt: square root of x tan : return x (x in radians) tangent trunc: returns the integer part of x --------------------- author: changaspl source: CSDN original: https: / /blog.csdn.net/qq_40674583/article/details/81940974 Disclaimer: This article is a blogger original article, reproduced, please attach Bowen link!
