Description

This is unfortunate:

julia> float32("1f0")
ERROR: ArgumentError("float32(String): invalid number format")
 in float32 at string.jl:1567

Contributor guide

Research direction
Examine the float32 parsing implementation in base/parse.jl and add support for the 'f' exponent character (e.g., 1f0).
