Float

Function: float (<expr>) Converts integers, rational numbers and bigfloats in <expr> to floating point numbers. It is also an evflag, float causes non-integral rational numbers and bigfloat numbers to be converted to floating point.

a:7;
b:8;
float(sqrt(a^2+b^2));
f(x):=x^2-x+1;
f(3);
f(a);
f(b);
log10(x):=log(x)/log(10);
float(log10(3));
(30!);

There are also some inexact matches for float. Try ?? float to see them.
