Thanks David, but it didn't work.
When I echo each variable out, here's the finding:
$mp_price: RM 450.00
$currency: empty
$number: RM 450.00

if I change
$number = substr( $mp_price, strpos( $mp_price, ' ' ) + 1 );
to
$number = substr( $mp_price, strpos( $mp_price, ' ' ) - 1 );

which, a '+' to '-' and echo $number, I will get
"n class="mp_product_price"> RM 450.00"

I was thinking perhaps your function grab the last set of <space>xxx would work and filter everything else at the front, can it be done? For example the returned value could be <div whatever> RM 450, the function just grap the last set of the string by detecting the last space character?

Thanks so much Dave, hope to hear from you soon...

Ah yes - seen that now.
When you call mp_product_price then the first parameter defines whether you echo out the result or return it (the default is the former). Hence, if you modify my previous code so that mp_product_price() is now mp_produce_price(false) then it should work.
