what are the css font families?

The font-family property specifies the font for an element.
The font-family property can hold several font names as a "fallback" system. If the browser does not support the first font, it tries the next font.

There are two types of font family names:

family-name - The name of a font-family, like "times", "courier", "arial", etc.
generic-family - The name of a generic-family, like "serif", "sans-serif", "cursive", "fantasy", "monospace".


Start with the font you want, and always end with a generic family, to let the browser pick a similar font in the generic family, if no other fonts are available.

Note: Separate each value with a comma.

Note: If a font name contains white-space, it must be quoted. Single quotes must be used when using the "style" attribute in HTML.

I have written a set of functions to compute basic mathematical operations for my own Java-based programming language. First I tokenize input from the source code file and store it in a String array. For the mathematics, I simply read through the array looking for an operator (+, -, /, *) and if I find one I call a operation function. The language needs to be able to automatically handle double/int mathematics without additional casting or indication so obviously this complicates the functions. However, my question is, are these functions really the simplest and most efficient way to do basic math operations?: (Note, I have 4 just like this, one for each basic operation, just copy/pasted the same code with minor changes. That feels repetitive. Isn't there a better way to do this also along with the shortening of each function?)

Example:

5.32 + 7 returns 12.32

My Number Parser:

NumReturn numberParser(int cIndex) {
                 NumReturn nri;
                  NumReturn nrd;
                 try {
                         nri = new NumReturn(Integer.parseInt(Lexer.token[cIndex]), cIndex++, 'i');
                         System.out.println(nri.value + " ");
                         return nri;
                 } catch (NumberFormatException intExcep) {
                 }
                 try {
                         nrd = new NumReturn(Double.parseDouble((Lexer.token[cIndex])), cIndex++, 'd');
                         System.out.println(nrd.dvalue + " ");
                         return nrd;
                 } catch (NumberFormatException doubExcep) {
                         // doubExcep.printStackTrace();
                 }
                 return null;
         }`
