Types

type Number

type Number float64

Number represents a JS-like number.

All operations that can be performed directly on this type (e.g., conversion, arithmetic, etc.) behave as they would in JavaScript, but any other operation should use this type's methods, not the "math" package and conversions.

const (
	MaxSafeInteger Number = 1<<53 - 1
	MinSafeInteger Number = -MaxSafeInteger
)

type PseudoBigInt

type PseudoBigInt struct {
	Negative    bool   // true if the value is a non-zero negative number.
	Base10Value string // The absolute value in base 10 with no leading zeros. The value zero is represented as an empty string.
}

PseudoBigInt represents a JS-like bigint. The zero state of the struct represents the value 0.
