php - Check if variable with a number stored as contains a decimal point -

i'm checking if custom field has decimal, , adding ".0" if doesn't.

for reason, keep getting incorrect outputs: adds decimal either way.

function containsdecimal( $value ) { if ( strpos( $value, "." ) !== false ) {   echo "$value.0"; } else { echo "$value"; }} 

and call:

<?php containsdecimal(the_field('carbs-g')); ?> <?php containsdecimal(the_field('fiber-g')); ?> 

with carbs-g = 1.2 , fiber-g = 0...

this returns: 1.2.0 , 0.0

when use call correct results:

<?php containsdecimal(1.2); ?> <?php containsdecimal(0); ?> 

this returns: 1.2 , 0.0

your logic backwards :-)

you adding ".0" when number has decimal (the strpos result isn't false).
should adding when strpos result is false (the number doesn't have decimal).

function containsdecimal( $value ) {     if ( strpos( $value, "." ) === false ) {       echo "$value.0";     } else {     echo "$value"; } }
