Multiplies an floating point value x by Template:cpp raised to power exp. On binary system it is equivalent to ldexp()
Parameters
| arg | - | floating point value |
| exp | - | integer value |
Return value
returns x×FLT_RADIXexp
If the result is too large for the underlying type, range error occurs and Template:cpp is returned.
