a!currency: force recognize "," instead of "." as decimal

Question

My application is specifically for a local where the decimal symbol used is comma " , " and not a period " . ". So, the decimals will be inputted by the portal users as `5,55` instead of `5.55` 
 So my current code is the following: 
 a!textField(
 label: "The amount of money for payment",
 labelPosition: "ABOVE",
 instructions: "",
 helpTooltip: "The amount of money for payment",
 value: if(
 local!variant_value_for_payment > 0,
 a!currency(
 isoCode: "BRL",
 value: local!variant_value_for_payment,
 format: "LOCALE"
 ),
 null
 ),
 saveInto: {
 a!save(
 local!variant_value_for_payment,
 todecimal(save!value)
 )
 },
 refreshAfter: "KEYPRESS"
), 
 
 I've read the a!currency docs and the main question for the best solution for me should be: 
 &rarr; How may I be able to forcely make the system reads "100.50" and recognizes as " 100.00" and keeps that format? 
 Thanks from now on

For your first question of reading with ","... Use Substitute(), Hope the following code helps 
 a!localVariables(
 local!variant_value_for_payment,
 local!valueforpayment: a!refreshVariable(
 value: if(
 a!isNullOrEmpty(local!variant_value_for_payment),
 null,
 todecimal(
 fn!substitute(
 local!variant_value_for_payment,
 ",",
 "."
 )
 )
 ),
 refreshOnVarChange: local!variant_value_for_payment
 ),
 a!textField(
 label: "The amount of money for payment",
 labelPosition: "ABOVE",
 instructions: "",
 helpTooltip: "The amount of money for payment",
 value: if(
 local!variant_value_for_payment > 0,
 a!currency(
 isoCode: "BRL",
 value: local!valueforpayment,
 format: "LOCALE"
 ),
 null
 ),
 saveInto: {
 a!save(
 local!variant_value_for_payment,
 save!value
 )
 },
 refreshAfter: "KEYPRESS"
 ),
 
)
