Hey all,

I'm using C++ and the djgpp compiler to write mathematical models.  For
exponents, I've written my equations as "a^b" to signify 'take a to the b
power'.  However, the compiler complains "invalid operands 'float' and
'double' to binary 'operator ^'".  What is the proper mathematical operator
for exponent?  If '^' is the proper operator, then what am I missing?  A
sample line of code might be:

numberFemales = survival^0.226175;

where all variables are initialized as float, double, or long double.
Please send responses to e-mail:
