What does this number mean "1.990000E+001"?

In a script like below:

exampleMc.gotoAndPlay(_loc1 * 1.990000E+001 + 1);

What exactly is the number 1.990000E+001?

Thanks,

19.9

you can always use the trace() function.

Thanks for the answer. Is there a page explaining this E + thing? Why does it use a numbering system like this instead of just putting 19.9?

that's exponential or scientific notation.  so,

1.99E+001 = 1.99 x 10(to the 1 power) = 1.99x10 = 19.9

1.00E-002 = 1.00 x 10(to the -2 power) = 1.99/10^^2 = .0199

that's often used to express small or large numbers and is easier to read than writing the decimal representation.  the code you posted looks like it was generated by a decompiler program and may have its own reasons for using scientfic notation instead of decimal notation.
