Python | frexp() Function freexp() 函数是 Python 中的标准数学库函数之一。 它返回尾数和指数作为给定值 x 的对 (m, e),其中尾数 m 是浮点数,e 指数是整数值。 m 是一个浮点数,e 是一个整数,使得 x == m * 2**e 正好。 如果x 为零,则返回 (0.0, 0),否则返回 0.5 <= abs(m) < 1。...

double frexp(double x, int *exponent) The frexp() function is used to break down the floating-point value x into a term m for the mantissa and another term n for the exponent. Parameters: Return value from frexp() Returns the mantissa term m. If x is 0, frexp() returns 0 for both...

math.frexp() function Flux 0.22.0+ View InfluxDB support math.frexp() breaks f into a normalized fraction and an integral part of two. It returns frac and exp satisfying f == frac x 2**exp, with the absolute value of frac in the interval [1/2, 1). ...
The frexp function breaks down the floating-point value (x) into a mantissa (m) and an exponent (n), such that the absolute value of m is greater than or equal to 0.5 and less than 1.0, and x = m*2n. The integer exponent n is stored at the location pointed to by expptr. ...
frexp- extract mantissa and exponent from double precision number SYNOPSIS #include <math.h> double frexp(double num, int *exp); DESCRIPTION The frexp() function breaks a floating-point number into a normalized fraction and an integral power of 2. It stores the integer exponent in the int ob...
