Stamina's needed to get the decimal part of a logarithm (8)
I believe the answer is:
mantissa
'the decimal part of a logarithm' is the definition.
(I've seen this in another clue)
'stamina's needed to' is the wordplay.
'stamina's' anagrams to 'MANTISSA'.
However, I'm not sure how the anagram is indicated.
'get' is the link.
Can you help me to learn more?
(Other definitions for mantissa that I've seen before include "the end of logarithms!" , "Fraction of log" , "It's beside the point" , "Part of logarithm following decimal point" , "Part of log" .)
