Description:

• single is both a function and a constant.
• As a function, it rounds its argument to the nearest IEEE 754 single precision (i.e. IEEE754-2008 binary32) number. Subnormal numbers are supported as well as standard numbers: it is the real rounding described in the standard.
• As a constant, it symbolizes the single precision format. It is used in contexts when a precision format is necessary, e.g. in the commands round and roundcoefficients. In is not supported for implementpoly. See the corresponding help pages for examples.
