Guardian Native C Library Calls (f) fmin(3)
NAME
fmin - Determines the minimum numeric value of two floating-point numbers
LIBRARY
H-series and J-series native Guardian processes: $SYSTEM.ZDLLnnn.ZCREDLL
32-bit H-series and J-series OSS processes: /G/system/zdllnnn/zcredll
64-bit H-series and J-series OSS processes: /G/system/zdllnnn/ycredll
SYNOPSIS
#include <math.h>
double fmin(
double x,
double y
);
PARAMETERS
x Specifies a double number.
y Specifies a double number.
DESCRIPTION
The fmin() function determines the minimum numeric value of two floating-point numbers.
NaN arguments are treated as missing data. If one argument is a NaN and the other numeric, the
fmin() function returns the numeric value.
NOTES
This function is implemented only for the IEEE_float floating-point option. Applications using
this function cannot be compiled if the specified floating-point option is Tandem_float.
RETURN VALUES
Upon successful completion, the fmin( ) function returns the minimum numeric value of x and y.
If one argument is a NaN and the other numeric, the fmin( ) function returns the numeric value.
If both x and y are NaNs, the fmin() function returns NaN.
ERRORS
No errors are defined.
