This patch allows exponential notation for numbers. Here are some examples with comments: x = 1e+2 print x, x.GetType() //100 int x2 = 1e2 //the + sign is optional print x2, x2.GetType() //100 x4 = 1.1e+2 //use a decimal point for better precision print x4, x4.GetType() //110 double x5 = 1.1e-2 //minus sign for negative exponents (but use decimal point since this is not for integers) print x5, x5.GetType() //0.011 x6 = 1e+2L //you can use the L suffix print x6, x6.GetType() //100 long x7 = 6e+2s //timespans work as well print x7, x7.GetType() //10:00 x8 = 10.0e-4h print x8, x8.GetType() //3.6 seconds x9 = .9e2 //numbers that start with a decimal point work print x9, x9.GetType() //90 This syntax also works in interpolated expressions.
