3.1 Exponentials and Logarithms ¶

Operator: exp expression ¶

Represents the exponential function of scalar expression.

(%0043) exp(1+x);
%0043: exp(1 + x)
(%0044) exp(0);
%0044: 1

Operator: log expression ¶

Represents the natural logarithm of scalar expression.

(%0045) log(1+x);
%0045: log(1 + x)
(%0046) exp(5*log(a));
        5
%0046: a

Operator: %expt expression exponent ¶

%expt is equivalent to exponent*log(expression). If exponent is an integer, it simplifies to a power of expression; a fractional exponent does not.

(%0048) %expt(a,5);
        5
%0048: a
(%0049) %expt(a,1/5);
           log(a)
%0049: exp(------)
             5
(%0050) a^(1/5);
        1/5
%0050: a
