WebDeciMath is an efficient-gas parent contract for fixed-point mathematics in Solidity. It offers basic decimal operations, and as well as transcendental functions - exp (x), ln (x) and pow (b, x) - for numbers of 18-decimal-place precision. Solidity does not support native fixed-point mathematics, so I made DeciMath.
