Anti-Log Function?

by aplonis (Pilgrim)
on Apr 26, 2019 at 00:51 UTC ( #1233002=perlquestion: print w/replies, xml ) Need Help??

aplonis has asked for the wisdom of the Perl Monks concerning the following question:

Is there an anti-log function in Perl? Or lacking that, an example somewhere of doing inverse logarithms? That is to say, the inverse of a natural log?

Replies are listed 'Best First'.

    The function exp is the 'antilog'.

    I suppose you might have missed that log is the "natural log" in Perl:

    from perldoc

    log

    Returns the natural logarithm (base e) of EXPR.

    ...

    See also exp for the inverse operation.

    exp is the 'anti-log' Returns e (the natural logarithm base) to the power of EXPR. If EXPR is omitted, gives exp($_).
