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.

eq1:R3/(R3+R2)*24=15;
eq2:(R3+R2)/(R1+R2+R3)*24=24-15;
eq3:R1+R2+R3=24/0.02;
solution:solve([eq1,eq2,eq3],[R1,R2,R3]);
eR1:solution[1][1];
eR2:solution[1][2];
eR3:solution[1][3];
float(eR3/(eR1+eR2+eR3)*24);

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