Abstract
A method of streamlining floating-point conversions includes determining a source coefficient and a source exponent of an input value represented by a floating-point number in a source base; estimating an approximated target exponent (ATE) using the source coefficient and the source exponent, in the event the source coefficient has a non-zero value; determining whether the ATE exceeds a maximum exponent so as to result an overflow, and outputting a predefined overflow value in the event of an overflow; determining whether the ATE exceeds a minimum exponent so as to result an underflow, and outputting a predefined underflow value in the event of an underflow; and in the event the ATE does not result in either an overflow or underflow, converting the input value to an output value represented by a converted coefficient, a converted base and the exponent of the output value.
