I'm about 99% sure that you would put in an exponent like 34*10^2

from the kochan bok

(3.31 x 10e8 x + 2.01 x 10e7)
the 'e' can be lower or upper case

(3.31 x 10e8 x + 2.01 x 10e7)
the 'e' can be lower or upper case

Actually, that's not correct. The 'e' means "times 10 to the power of", so if you say 10e8, you're actually saying "10 times 10 to the 8th power", which is 10 to the 9th power--not what you want.

You shouldn't use the multiplication operator at all: just type "3.3e8," "2.01e-7", etc.

#import <Foundation/Foundation.h>

int main (int argc, const char * argv[]) {
NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];

// insert code here...
NSLog(@"%g",(3.31e-8 + 2.01e-7) / (7.16e-6 + 2.01e-8) );
[pool drain];
return 0;
}

/* 0.032604 */

right

I was only showing the notation not correcting what i "thought" he meant by his expression.
