FLOAT(3) BSD Library Functions Manual FLOAT(3)
float — functions with single-precision floating-point arguments
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, with‐
out 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".
The following functions are also available in single precision. The func‐
tions 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.
