Question

I am reading in a text file with tons of values in this format: 1.36E-08

Is there a way to “parse” (i think thats the word i need) this value into a double? If I assign it straight forward it gives me 0.

//this NSLogs out "0.00000"
double x = 1.36E-08;

Answer 1

I think You want this:

NSDecimalNumber *decNumber = [NSDecimalNumber decimalNumberWithString:@"1.36e-08"];

NSLog(@"Number -> %g", [decNumber doubleValue]);

Output:

Number -> 1.36e-08
