Webmath.frexp () function exists in Standard math Library of Python Programming Language. This function returns mantissa and exponent as a pair (m, e) of a given value x, where … WebMay 29, 2016 · The exponent is always the number of times the mantissa pattern needs to be multiplied by 10 to obtain a value equal to the "regular number". In standard scientific notation, the mantissa is always written with one non-zero digit to the left of the decimal point. So, for example, while 847.13 × 101 is in scientific notation (with a mantissa of ...
