val default_printing_conf : printing_confDefault printing configuration
Mark a positive integer value with thousand separator configuration e.g. mark_thousands ~v: 1234567 ~sep: "," would print "1,234,567"
val q_to_decimal : printing_conf:printing_conf -> qv:Q.t -> stringConvert a rational value to string representation of a float value with a printing configuration. e.g. let sep_dot_comma = Separator.make_exn ('.', Some ',') in
let printing_conf = { separator = sep_dot_comma; plus_sign = true; num_of_digits = Uint8.of_int 4; rounding = Truncate } in
q_to_decimal ~printing_conf: printing_conf ~qv: (Utils.make_q "-1234567/7") would print "-176366.7142"
Convert an integer value to float/decimal value of string rep, not used internally but provide mere convenience
val unsafe_decimal_to_q :
decimal:string ->
sep:Separator.t ->
(string, string) Stdlib.resultParse the string representation of a float value with printing configuration e.g. let sep = Separator.make_exn ('.', Some ',') in unsafe_decimal_to_q ~decimal : "+123,456.789" would convert value to "123456.789"
Unsafely convert a float/decimal value of string rep to integer value. It is unsafe in a sense that the origin of float/decimal is deemed to be unverified by default and might be as a result of lossy operations.
val seal_quotient :
printing_conf:printing_conf ->
qv:Safemoney.Quotient.t ->
stringConvert quotient value to the string representaion of a float value with a printing configuration. This should be used as the final step after all operations have been carried out.
val seal_discrete :
printing_conf:printing_conf ->
dv:Safemoney.Discrete.t ->
stringConvert discrete value to the string representaion of a float value with a printing configuration. This should be used as the final step after all operations have been carried out.
val seal_exchange :
printing_conf:printing_conf ->
xchg:Safemoney.Exchange.t ->
stringConvert exchange value to the string representaion of a float value with a printing configuration. This should be used as the final step after all operations have been carried out.
val seal_scale :
printing_conf:printing_conf ->
scale:Safemoney.Discrete.Scale.t ->
stringConvert scale value to the string representaion of a float value with a printing configuration. This should be used as the final step after all operations have been carried out.
val unsafe_float_to_quotient :
symbol:string ->
decimal:string ->
sep:Separator.t ->
Safemoney.Quotient.tUnsafely convert a float/decimal value of string rep to quotient value. It is unsafe in a sense that the origin of float/decimal is deemed to be unverified by default and might be as a result of lossy operations.
val unsafe_float_to_discrete :
scale:Safemoney.Discrete.Scale.t ->
integer:int ->
Safemoney.Discrete.tUnsafely convert a integer value of string rep to discrete value. It is unsafe in a sense that the origin of the integer is deemed to be unverified by default and might be as a result of lossy operations.
val unsafe_float_to_exchange :
src:string ->
dst:string ->
decimal:string ->
sep:Separator.t ->
Safemoney.Exchange.tUnsafely convert a float/decimal value of string rep to exchange value. It is unsafe in a sense that the origin of float/decimal is deemed to be unverified by default and might be as a result of lossy operations.
val unsafe_float_to_scale :
symbol:string ->
unit:string ->

Safemoney.Discrete.Scale.tUnsafely convert a float/decimal value of string rep to scale value. It is unsafe in a sense that the origin of float/decimal is deemed to be unverified by default and might be as a result of lossy operations.
