Convert various types to other types, e.g. int -> string.
Procs
func toFloat(c: char): float {....raises: [ValueError], tags: [], forbids: [].}
-
Convert a digit, represented as a char, to float.
Example:
doAssert '0'.toFloat == 0.0 doAssert '5'.toFloat == 5.0
func toFloat(f: float): float {....raises: [], tags: [], forbids: [].}
-
Convert a float to float.
It seems useless, but if you don't know the exact type of a variable in a chain and it happens to be a float, it does no harm.
Example:
doAssert (3.14).toFloat == 3.14
func toFloat(s: string): float {....raises: [ValueError], tags: [], forbids: [].}
-
Convert a string to float.
Example:
doAssert "3.2".toFloat == 3.2
func toInt(digit: char): int {....raises: [ValueError], tags: [], forbids: [].}
-
Convert a digit, represented as a char, to int.
Example:
doAssert '0'.toInt == 0 doAssert '5'.toInt == 5
func toInt(n: int): int {....raises: [], tags: [], forbids: [].}
-
Convert an int to int.
It seems useless, but if you don't know the exact type of a variable in a chain and it happens to be an int, it does no harm.
Example:
doAssert 2.toInt == 2 doAssert 123.toInt == 123
func toInt(s: string): int {....raises: [ValueError], tags: [], forbids: [].}
-
Convert a string to int.
Example:
doAssert "42".toInt == 42 doAssert "-576".toInt == -576
func toIntPart(f: float): int {....raises: [], tags: [], forbids: [].}
-
Convert a float to int and keep just the integer part.
Keep just the integer part, do no rounding. Python's int(...) works like this. However, system.toInt(f: float): int does rounding.
Example:
doAssert (3.2).toIntPart == 3 doAssert (3.8).toIntPart == 3 doAssert (-3.2).toIntPart == -3 doAssert (-3.8).toIntPart == -3
