scalb(3M) scalb(3M)[top]NAMEscalb(), scalbf(), scalbl(), scalbw(), scalbq() - scale exponent of a radix-independent floating-point numberSYNOPSISHP Integrity Server OnlyDESCRIPTIONThe function returns where r is the radix of the machine's floating- point arithmetic. The radix r is 2 on all PA-RISC and Integrity servers. Integrity Server Only is a version of it takes arguments and returns a result. is a version of it takes arguments and returns a result. is an version of it takes arguments and returns an result. is equivalent to on HP-UX systems.USAGETo use these functions, compile either with the default option or with the and options. To use (for Integrity servers) or compile also with the option. Make sure your program includes Link in the math library by specifying on the compiler or linker command line.RETURN VALUEand are equivalent. If y returns x. If x is +0 and y is +INFINITY, returns a NaN and raises the invalid exception. If x is +0 and y is an integer less than +INFINITY, returns +0. If x is +INFINITY and y is an integer greater than −INFINITY, returns +INFINITY. If x is finite and positive-signed and y is −INFINITY, returns +0. If x is positive and y is +INFINITY, returns +INFINITY. If x is +INFINITY and y is −INFINITY, returns a NaN. If x or y is NaN, returns a NaN. returns a properly signed infinity in lieu of a value whose magnitude is too large, and raises the overflow and inexact exceptions. raises the underflow and inexact exceptions whenever a result is tiny (essentially denormal or zero) and thereby suffers loss of accuracy, and may raise those exceptions if the result is merely tiny.ERRORSIf the correct value would overflow or underflow, sets to [ERANGE]. Integrity Server Only HP-UX functions on Integrity servers do not set by default. For set‐ ting, compile with the option.SEE ALSOscalbn(3M), scalbln(3M), ilogb(3M), ldexp(3M), logb(3M), math(5).STANDARDS CONFORMANCE: ISO/IEC C99 (including Annex F, ``IEC 60559 floating-point arith‐ metic'') scalb(3M)
