module Checked

Value

Description

( * ) : ^T1 -> ^T2 -> ^T3

Overloaded multiplication operator (checks for overflow).

( + ) : ^T1 -> 'T2 -> 'T3

Overloaded addition operator (checks for overflow).

( - ) : ^T1 -> ^T2 -> ^T3

Overloaded subtraction operator (checks for overflow).

( ~- ) : ^T -> ^T

Overloaded unary negation (checks for overflow).

byte : ^T -> byte

Converts the argument to byte. This is a direct, checked conversion for all primitive numeric types. For strings, the input is converted using Parse with InvariantCulture settings. Otherwise the operation requires an appropriate static conversion method on the input type.

char : ^T -> char

Converts the argument to char. Numeric inputs are converted using a checked conversion according to the UTF-16 encoding for characters. String inputs must be exactly one character long. For other input types the operation requires an appropriate static conversion method on the input type.

int : ^T -> int

Converts the argument to int. This is a direct, checked conversion for all primitive numeric types. For strings, the input is converted using Parse with InvariantCulture settings. Otherwise the operation requires an appropriate static conversion method on the input type.

int16 : ^T -> int16

Converts the argument to int16. This is a direct, checked conversion for all primitive numeric types. For strings, the input is converted using Parse with InvariantCulture settings. Otherwise the operation requires an appropriate static conversion method on the input type.

int32 : ^T -> int32

Converts the argument to int32. This is a direct, checked conversion for all primitive numeric types. For strings, the input is converted using Parse with InvariantCulture settings. Otherwise the operation requires an appropriate static conversion method on the input type.

int64 : ^T -> int64

Converts the argument to int64. This is a direct, checked conversion for all primitive numeric types. For strings, the input is converted using Parse with InvariantCulture settings. Otherwise the operation requires an appropriate static conversion method on the input type.

nativeint : ^T -> nativeint

Converts the argument to nativeint. This is a direct, checked conversion for all primitive numeric types. Otherwise the operation requires an appropriate static conversion method on the input type.

sbyte : ^T -> sbyte

Converts the argument to sbyte. This is a direct, checked conversion for all primitive numeric types. For strings, the input is converted using Parse with InvariantCulture settings. Otherwise the operation requires an appropriate static conversion method on the input type.

uint16 : ^T -> uint16

Converts the argument to uint16. This is a direct, checked conversion for all primitive numeric types. For strings, the input is converted using Parse with InvariantCulture settings. Otherwise the operation requires an appropriate static conversion method on the input type.

uint32 : ^T -> uint32

Converts the argument to uint32. This is a direct, checked conversion for all primitive numeric types. For strings, the input is converted using Parse with InvariantCulture settings. Otherwise the operation requires an appropriate static conversion method on the input type.

uint64 : ^T -> uint64

Converts the argument to uint64. This is a direct, checked conversion for all primitive numeric types. For strings, the input is converted using Parse with InvariantCulture settings. Otherwise the operation requires an appropriate static conversion method on the input type.

unativeint : ^T -> unvativeint

Converts the argument to unativeint. This is a direct, checked conversion for all primitive numeric types. Otherwise the operation requires an appropriate static conversion method on the input type.
