This is a Java SE 8 project that takes a number as an input and outputs a prettified string representation.

Numbers with 6 digits or less simply returns the exact input in string format.

Numbers in the millions, billions and trillions return a prettified string representation.

Examples:

input: 532
output: 532

input: 1000000
output: 1M

input: 2500000.34
output: 2.5M

input: 1123456789
output: 1.1B

input: 9487634567534
output: 9.5T
