...prefixing ciphers. NOTE. — When a decimal number is to be multiplied by 10, 100, 1000, &c., remove the decimal point as many places to the right as there are ciphers in the multiplier; and if there be not figures enough in the number, Annex ciphers. Thus, 1.25 X 10 = 12.5 ; and 1-7 X 100 = 170. Proof.... | |
