All MIPS FPUs need it; the architecture specification leaves it to the
implementor of a CPU which parts of the FP architecture are implemented
in hardware if at all; the missing parts have to be replaced in
software.

This piece of code shouldn't result in any FPU operations as printf is
very careful to avoid inaccuracies that might result from floating point
operations.
