It looks like one of the most notable contributions is he helped to popularize the graphical representation of complex numbers. (see link)
Basically it means change. It can meanchange a measurement from one set of units to another - for example convert the distance from miles to kilometres, orchange a number from one form of representation to another for example, convert a number from a fraction to scientific notation.
To convert the number 110 into a decimal, you simply write it as 110.0. This indicates that there are no fractions or parts of a whole number present, making it a whole number in decimal form. In this case, the decimal representation is the same as the original number, 110.
Complex numbers whose polar representation is (r, theta) where 3*pi/2 < theta < 2*pi.
If the discriminant - the part under the radical sign in the quadratic formula - is negative, then the result is complex, it is as simple as that. You can't convert a complex number to a real number. If a particular problem requires only real-number solutions, then - if the formula gives complex numbers - you can state that there is no solution.

A decimal number is simply a way of representing a number in such a way that the place value of each digit is ten times that of the digit to its right. A decimal representation does not require a decimal point. So the required decimal representation is 1517, exactly as in the question.
