Math.Pow gives “Cannot implicitly convert type 'double' to 'float' ” error

Question

In this program I am trying to create a simple calculator. However, I can\'t seem to find a way to overcome the aforementioned error when reaching the Math.Pow line

Answer 1

Use double instead of float for your variables.

The float data type has quite limited precision, so the rounding errors (that are always present in floating point arithmetics) are relatively large.

The reason that you see the wrong result of the square and square root, is that you never show the result at all. Change one of the {0} in each format string into {1}:

Console.WriteLine(" {0} squared results in {1}",x, power);
Console.WriteLine(" Square root of {0} is: {1}", x, sqrt);
