If the exponent is non-integral, it is truncated. The valid range of the exponent is platform specific, but is at least -2147483648 to 2147483647. &bc.scale.description; &reftitle.returnvalues; Returns the result as a string. &reftitle.changelog; &Version; &Description; 7.3.0 bcpow now returns numbers with the requested scale.

This only occurs when the result doesn't require all of the precision allowed by the scale. For example: ]]> &reftitle.seealso; bcpowmod bcsqrt
