NAME
     float -- functions with single-precision floating-point arguments

DESCRIPTION
     The following functions are available in single precision. The functions conform to the ISO/IEC 9899:1999(E) standard. They are similar to
     the corresponding double-precision functions (which have the same name, without the "f" at the end). The double-precision functions have
     their own pages. Wherever the double-precision functions use a double-precision floating-point value (as an argument or return value), these
     functions use a single-precision floating-point value.

     To use these functions you must add an additional flag to the link step that produces the executable binary. Specify "-lmx".

     acosf()

     acoshf()

     asinf()

     asinhf()

     atanf()

     atan2f()

     atanhf()

     cbrtf()

     cosf()

     coshf()

     erff()

     erfcf()

     hypotf()

     logf()

     log2f()

     log10f()

     log1p()

     powf()

     sinf()

     sinhf()

     sqrtf()

     tanf()

     tanhf()

     The following functions are also available in single precision. The functions conform to the ISO/IEC 9899:1999(E) standard. Each one has its
     own page, which it shares with its corresponding double-precision function (which has the same name, without the "f" on the end). The page
     can be found under both names.

     You do not need to specify the "-lmx" flag to use these functions.
