NAME
echo - echo arguments to standard output SYNOPSIS
/usr/ucb/echo [-n] [argument] DESCRIPTION
echo writes its arguments, separated by BLANKs and terminated by a NEWLINE, to the standard output. echo is useful for producing diagnostics in command files and for sending known data into a pipe, and for displaying the contents of envi- ronment variables. For example, you can use echo to determine how many subdirectories below the root directory (/) is your current directory, as follows: o echo your current-working-directory's full pathname o pipe the output through tr to translate the path's embedded slash-characters into space-characters o pipe that output through wc -w for a count of the names in your path. example% /usr/bin/echo "echo $PWD | tr '/' ' ' | wc -w" See tr(1) and wc(1) for their functionality. The shells csh(1), ksh(1), and sh(1), each have an echo built-in command, which, by default, will have precedence, and will be invoked if the user calls echo without a full pathname. /usr/ucb/echo and csh's echo() have an -n option, but do not understand back-slashed escape characters. sh's echo(), ksh's echo(), and /usr/bin/echo, on the other hand, understand the black-slashed escape characters, and ksh's echo() also understands a as the audible bell character; however, these commands do not have an -n option. OPTIONS
-n Do not add the NEWLINE to the output. ATTRIBUTES

The -n option is a transition aid for BSD applications, and may not be supported in future releases. SunOS 5.10 3 Aug 1994 echo(1B)

ROUND(3)								 1								  ROUND(3)

round - Rounds a float

SYNOPSIS
float round (float $val, [int $precision], [int $mode = PHP_ROUND_HALF_UP]) DESCRIPTION
Returns the rounded value of $val to specified $precision (number of digits after the decimal point). $precision can also be negative or zero (default). Note PHP doesn't handle strings like "12,300.2" correctly by default. See converting from strings. PARAMETERS
o $val - The value to round o $precision - The optional number of decimal digits to round to. o $mode - Use one of the following constants to specify the mode in which rounding occurs. +--------------------+---------------------------------------------------+ | Constant | | | | | | | Description | | | | +--------------------+---------------------------------------------------+ | | | | PHP_ROUND_HALF_UP | | | | | | | Round $val up to $precision decimal places away | | | from zero, when it is half way there. Making 1.5 | | | into 2 and -1.5 into -2. | | | | | | | |PHP_ROUND_HALF_DOWN | | | | | | | Round $val down to $precision decimal places | | | towards zero, when it is half way there. Making | | | 1.5 into 1 and -1.5 into -1. | | | | | | | |PHP_ROUND_HALF_EVEN | | | | | | | Round $val to $precision decimal places towards | | | the next even value. | | | | | | | |PHP_ROUND_HALF_ODD | | | | | | | Round $val to $precision decimal places towards | | | the next odd value. | | | | +--------------------+---------------------------------------------------+ RETURN VALUES
