#### Bfloat

Function: bfloat (<expr>) Converts all numbers and functions of numbers in <expr> to bigfloat numbers. The number of significant digits in the resulting bigfloats is specified by the global variable `fpprec`.

When `float2bf` is `false` a warning message is printed when a floating point number is converted into a bigfloat number (since this may lead to loss of precision).

There are also some inexact matches for `bfloat`. Try `?? bfloat` to see them.

```(%o1)                                true
(%i2) ```
