I have a question about exponents in for decimal float exponents.

Decimal 

 let decimalTest = 2e3

which is 

2 * 10^3 = 2000

Hexadecimal 

let hexaTest = 0x2p3

which is 

2 * 2^3 = 16

Why would the hexadecimal be multiplied by an exponent with a base of 2 instead of 16?

edit: formatting & forgot to declare hexadecimal for the hexaTest
