exp2(3M) exp2(3M) NAME
exp2(), exp2f(), exp2l(), exp2w(), exp2q() - base-2 exponential functions SYNOPSIS
HP Integrity Server Only DESCRIPTION
returns Integrity System Only is a version of it takes a argument and returns a result. is a version of it takes a argument and returns a result. is an version of it takes an argument and returns an result. is equivalent to on HP-UX systems. USAGE
To 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. To use these functions, make sure your program includes and link in the math library by specifying on the compiler or linker command line. For more information, see the at the following site: RETURN VALUE
returns 1. If x is +INFINITY, returns +INFINITY. If x is -INFINITY, returns zero. If x is NaN, returns NaN. returns infinity (equal to 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. raises the inexact exception whenever a rounded result does not equal the mathematical result. ERRORS
Integrity Server Only If the correct value would overflow, sets to [ERANGE]. HP-UX functions on Integrity servers do not set by default. For setting, compile with the option. SEE ALSO

To use these functions compile either with the default option or with the and the options. To use (for Integrity servers) or compile also with the option. To use any of these functions, make sure your program includes and link in the math library by specifying on the compiler or linker command line. For more information, see the at the following site: PA-RISC Only Millicode versions of the functions are available. Millicode versions of math library functions are usually faster than their counterparts in the standard library. To use these versions, compile your program with the or the optimization option. For special cases, the millicode versions return the same values as their standard library counterparts (see the section), but do not set RETURN VALUE

If x is NaN, returns NaN. returns infinity (equal to 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. When it raises no other exception, whether raises the inexact exception is unspecified. ERRORS
