Editing IEEE 754-1985 (section)

===Standard operations===
The following functions must be provided:
*[[arithmetic operations|Add, subtract, multiply, divide]]
*[[Square root]]
*Floating point remainder. This is not like a normal [[modulo operation]], it can be negative for two positive numbers. It returns the exact value of {{math|x–(round(x/y)·y)}}.
*[[rounding to integer|Round to nearest integer]]. For undirected rounding when halfway between two integers the even integer is chosen.
*Comparison operations. Besides the more obvious results, IEEE&nbsp;754 defines that −∞&nbsp;=&nbsp;−∞, +∞&nbsp;=&nbsp;+∞ and <var>x</var>&nbsp;≠&nbsp;<code>NaN</code> for any <var>x</var> (including <code>NaN</code>).
