Abstract

PURPOSE:To limit the upper limit of a random number by an input numeral by providing a register stored with the output signal of a random-pulse generating circuit as numeral data below the decimal point, and a register stored with an optional integer value inputted externally. CONSTITUTION:In an (n)-digit register 2, numeral data below the decimal point is stored. To respective bits of the register 2, the outputs of (n) units of random pulse generating circuits 1 are inputted. In a register 3, numeral data of an integer part is stored. In a register 4, on the other hand, an external input value is stored. For example, an operator inputs a desired set value with numeric keys and the value is stored in the register 4. A multiplier 5 multiplies the vaues of the registers 2 and 4 by each other. Then, the integer part of the arithmetic result is stored in a register 6. The contents of the register 6 are outputted and displayed. In this case, the numeral of the register 6 is less than the input numeral without fail and a completely random value is outputted.
