UCLIBC_HAS_FPU:
If your target CPU does not have a Floating Point Unit (FPU) or a kernel FPU emulator, but you still wish to support floating point functions, then uClibc will need to be compiled with soft floating point support (-msoft-float). If your target CPU does not have an FPU or an FPU emulator within the Linux kernel, then you should answer N.

UCLIBC_HAS_FLOATS:
This option allows you to entirely omit all floating point number support from uClibc. This will cause floating point functions like strtod() to be omitted from uClibc. Other floating point functions, such as printf() and scanf() will still be included in the library, but will not contain support for floating point numbers.
Answering N to this option can reduce the size of uClibc. Most people will answer Y.
