We're not sure which side of the number is its behind.
We'd have to see it.
16 followed by 9 zeros ie 16 000 000 000
1x10^15 = one quadrillion 1x10^16 = ten quadrillion

Ten-thousand trillion has 16 zeros; this is also known as ten quadrillion One trillion = 1,000,000,000,000 (12 zeros) Ten trillion = 10,000,000,000,000 (13 zeros) One-hundred trillion = 100,000,000,000,000 (14 zeros) One-thousand trillion = 1,000,000,000,000,000 (15 zeros) (or one quadrillion) Ten-thousand trillion = 10,000,000,000,000,000 (16 zeros) (or ten quadrillion) That assumes the short scale (based on powers of a thousand plus 1) where thousand-trillion is not a normal moniker for a number - it would, as the answerer points out, be called ten quadrillion. The long scale (based on powers of a million) does use the moniker thousand-...illion for numbers (which are alternatively called ..illiard, eg 1000 million = 1 milliard, 1000 billion = 1 billiard, etc). In this case: 10 thousand trillion = 10000 x (106)3 = 104 x 1018 = 1022 and so has 22 zeros.
Ten Quintillion
A 16-bit binary number
There are 9 zeros in 16,000,000,000 which is 16 billion
16 followed by 9 zeros ie 16 000 000 000
We're not sure where the front and back of numbers are. The number you're describing is either any multiple of 1015 between 1015 and (1016 - 1), or else it's any number that more than 10-16 and less than 10-15 .
1x10^15 = one quadrillion 1x10^16 = ten quadrillion

108 = 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 = 100000000 (1 followed by 8 zeros). To work out 10 to the power of any whole number, put a 1 followed by the power number of zeros, for example 104 is 1 followed by 4 zeros (10000); 1016 is 1 followed by 16 zeros (10000000000000000).
