ABSTRACT:
A calculator for calculating a.sup.x with the base a of an optional positive number comprises a first circuit for calculating log.sub.10 a. A multiplier calculates x.multidot.log.sub.10 a,which is separated into an integral part z.sub.i and a fractional part z.sub.f. The integer z.sub.i represents the place of the decimal point in the desired result. A second circuit calculates 10.sup.z .sbsp.f which gives the desired result as a number equal to or greater than unity and smaller than ten. The number is stored in a register without the decimal point. With the decimal point put as indicated by the integer z.sub.i, the number gives the desired result. A second circuit may comprise a combination of operation registers, a multiplier, and an adder for calculating the power by combination of multiplication and addition.
