Currently we support the following SI prefixes (though as suffixes):

- Tera T = 1000000000000,
- Giga G = 1000000000
- Mega M = 1000000
- Kilo k = 1000
- Hecto h = 100
- Deca da = 10
- Deci d = 0.1
- Centi c = 0.01
- Milli m = 0.001
- Micro u = 0.000001
- Nano n = 0.000000001
- Pico p = 0.000000000001

- freqRC(r, c) for finding cutoff frequency in RC filter
- freqLC(l, c) for finding resonant frequency of LC filter
- impedanceLC(l, c) for finding impedance of LC filter
