Your friend have an issue with converting file sizes between B, KB, MB, GB and TB. Could you create converter that will help him?

Create class Converter that will have:

Properties:

• number that represent size amount (not necessarily integer).
• string that represent current unit type. Unit type can be only one of the next: 'B', 'KB', 'MB', 'GB', 'TB'

Methods:

• unit: return current unit type;
• size: return current size and unit as a string '19 MB' or '38.45 GB' or '7.5 TB'
• toB: convert size to Bytes and unit to 'B'
• toKB: convert size to Kilobytes and unit to 'KB'
• toMB: convert size to Megabyte and unit to 'MB'
• toGB: convert size to Gigabyte and unit to 'GB'
• toTB: convert size to Terabyte and unit to 'TB'

Note, that there can be maximum 3 digits after decimal and a number should be rounded to lower digit (floor)

Example:

var file = new Converter(1, "TB");

file.toMB();

file.unit; // 'MB'
file.size; // '1048576 MB'
