Jinja variable scope or how can I access integer which have been incremented inside loop? -

i have following jinja template: {% set counter = 0 %} {% f in somearray %} {% set counter = counter + 123 %} {% endfor %} // here want print {{counter}}, 0. i looked @ answer can jinja variable's scope extend beyond in inner block? did not help. tried create array variable , access it {% set counter = 0 %} {% set sz = [0] %} {% f in somearray %} {% set counter = counter + 123 %} {% set sz[0] = counter %} <---- crash here {% endfor %} jinja documentation says nothing array access... please help. to use array counter need modify code (and hacks!) show way of doing want without extensions. ok, main problem in code when set variable on jinja statement keeps value in scope (is local variable definition on function in python) , since jinja doesn't provide strightforward way of setting outside variables created on template need hacks. magic works using list: import jinja2 env = jinja2.environment() print env.from_string(""" {%- set coun

xml - XSLT : Converting int to float / double value -

i have xml file. how can convert int value double or float or vice versa using xslt? example, assume following source document : <a> <b> 22 </b> <a> result document <a> <b> 22.0 </b> <a> you can use format-number() function. <?xml version="1.0"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/xsl/transform"> <xsl:template match="@* | node()"> <xsl:copy> <xsl:apply-templates select="@* | node()"/> </xsl:copy> </xsl:template> <xsl:template match="b"> <b> <xsl:value-of select="format-number(., '#.0')" /> </b> </xsl:template> </xsl:stylesheet>

Endianness conversion cost on architectures -

today there 2 kinds of cpu architectrues, big endian , little endian. data needs converted between 2 representations. each cpu architecture, instruction set in particular, different , each allows different implementations changing endianness. cpus contain specific instructions while others not. my question this, today's architectures more efficient have data , convert on le architectures or other way around, in order minimize data conversion latency , maximize throughput in le communication. second question, can cost of conversion quantified, there data on matter? how costly conversion in java byte array? there data on specific jvms on specific architectures? different on dalvik? afaik relevant architectures x64, arm, mips , jvm/dalvik. missing any? data should in native endian except case copy value , send without processing. how can operations reversed endian (except bitwise operators)? network activities slower cpu, not compared ram. you'll hardly ever s
