of: Calculation, e.g. 20% of 100, 20 of 100
Math operators:
plus, + Addition, e.g. 1 plus 2, 1 + 2
minus, - Subtraction, e.g. 10 minus 6, 10 - 6
times, x, *, × Multiplication, e.g. 3 times 2, 3 multiplied by 2
by, divided, /, ÷ Division, e.g. 15 by 3, 15 divided by 3
power, ^, ** Exponentiation, e.g. 10 ^ 4, 2 to the power of 10
The operator is optional when units are present:
whats 2 m ft
whats 10% 100
Examples:
whats 2 meters in feet
whats 1.21 gigawatts in watts
whats 8 kg in grams
whats 1024 KiB in MiB
whats 3 times 2
whats 10 + 5
whats 15.4 divided by 2
whats 100 km per hour in mph
Multiplication:
whats 2 + 2 x 4
whats "(2 + 1) x 3"
Quote what the shell would otherwise expand, such as * and parentheses:
whats "4 * 3"
Units take part in arithmetic:
whats 2 m + 30 cm in ft
whats "(1 GB + 500 MB) in MB"
whats 100 km/h x 2
A percentage applies to the value on its left:
whats 100 + 10%
whats 100 - 10%
whats 100 x 10%
Compound units can be written as:
whats 100 km/h in mph
whats 100 mph in knots
Spaces are optional:
whats 2m ft
whats 1+1
Numbers may be signed or written in exponent notation:
