It should be used sparingly and with caution as it can cause offence, also bearing in mind that the real source of the problem might often be shortcomings in the usability of the system or opaque documentation."

Floating point is a method of representing such numbers in two parts: a mantissa represents the significant digits and an exponent tells you where the decimal point comes (or the binary point for binary numbers). This is similar to the scientific notation in which one and a half million..." current

Although more instructions may be needed for a given task, they can be made to run very fast and the silicon saved can be used for other optimisations such as large cache memories to speed up execution. The result can be a significant net gain in performance. ARM is the most widely used example of..." current
