TRADER_SAREXT(3) 1 TRADER_SAREXT(3)trader_sarext - Parabolic SAR - ExtendedSYNOPSIS
array trader_sarext (array $high, array $low, [float $startValue], [float $offsetOnReverse], [float $accelerationInitLong], [float
$accelerationLong], [float $accelerationMaxLong], [float $accelerationInitShort], [float $accelerationShort], [float $acceleration-
MaxShort])
DESCRIPTION PARAMETERS
o $high
- High price, array of real values.
o $low
- Low price, array of real values.
o $startValue
- Start value and direction. 0 for Auto, >0 for Long, <0 for Short. Valid range from TRADER_REAL_MIN to TRADER_REAL_MAX.
o $offsetOnReverse
- Percent offset added/removed to initial stop on short/long reversal. Valid range from 0 to TRADER_REAL_MAX.
o $accelerationInitLong
- Acceleration Factor initial value for the Long direction. Valid range from 0 to TRADER_REAL_MAX.
o $accelerationLong
- Acceleration Factor for the Long direction. Valid range from 0 to TRADER_REAL_MAX.
o $accelerationMaxLong
- Acceleration Factor maximum value for the Long direction. Valid range from 0 to TRADER_REAL_MAX.
o $accelerationInitShort
- Acceleration Factor initial value for the Short direction. Valid range from 0 to TRADER_REAL_MAX.
o $accelerationShort
- Acceleration Factor for the Short direction. Valid range from 0 to TRADER_REAL_MAX.
o $accelerationMaxShort
- Acceleration Factor maximum value for the Short direction. Valid range from 0 to TRADER_REAL_MAX.
RETURN VALUES
Returns an array with calculated data or false on failure.

nextafter, nexttoward - floating point number manipulation
SYNOPSIS
#include <math.h>
double nextafter(double x, double y);
float nextafterf(float x, float y);
long double nextafterl(long double x, long double y);
double nexttoward(double x, long double y);
float nexttowardf(float x, long double y);
long double nexttowardl(long double x, long double y);
DESCRIPTION
The nextafter() functions return the next representable neighbor of x in the direction towards y. The size of the step between x and the
result depends on the type of the result. If x = y the function simply returns y. If either value is NaN, then NaN is returned. Other-
wise a value corresponding to the value of the least significant bit in the mantissa is added or subtracted, depending on the direction.
The nexttoward() functions do the same as the nextafter() functions, except that they have a long double second argument.
These functions will signal overflow or underflow if the result goes outside of the range of normalized numbers.
CONFORMING TO
C99. This function is defined in IEC 559 (and the appendix with recommended functions in IEEE 754/IEEE 854).

Hi,
I've a table with values Low & High.
ex: NRA* - NZ99
If the input is NR20, the script should tell me which range it belongs to.
I was thinking of splitting the word into alphabets & then comapring each alphabet which is not a modest way.
I was wondering if there are any other ways to... (0 Replies)
Hello, all...
I've got an older HP-UX 11i machine hooked up to an HP VA array. I've never worked with VA arrays, so I was wondering if anyone could point me in the direction of some documentation on querying and manipulating VAs (HP VAs for Dummies or something).
I'm used to EMC arrays, so... (2 Replies)
Hi everyone,
I would like to ask if it is possible to gather SAR data on a specified time. let say yesterdays report, i want to get data at around 12PM and 5PM.
thank you. (2 Replies)
Hi everyone,
I'm having some trouble with float array.
When i try to get the array sum with float numbers i get this error line 39: soma + 2.34 | bc: syntax error: invalid arithmetic operator (error token is ".34 | bc")

Hi guys
I am faced with this problem that I couldn't figure out yet, if you can point me to some direction that'll be of great help. So here's what I want to do.
I have let's say 10000 files which contains same number of Z coordinates in each file. I have to find the distance of those... (6 Replies)
