IEEE abs operation.

Returns the arccosine of a float value. Corresponds to IEEE acos operation

Returns the arcsine of a float value. Corresponds to IEEE asin operation.

Returns the arctangent of a float value. Corresponds to IEEE atan operation.

Performs the 2-argument arctangent operation. Corresponds IEEE atan2(y, x) operation.

Returns the cube root of a float value. Corresponds to IEEE rootn(x, 3) operation.

Rounds a float up to the closest integral value.

Returns the cosine of a float value. Corresponds to IEEE cos operation.

Returns the hyperbolic cosine of a float value. Corresponds to IEEE cosh operation.

Raises Euler's number to a power. Corresponds to IEEE exp operation.

Rounds a float down to the closest integral value.

Returns the float that is represented in IEEE 64-bit floating point by x. All bit patterns that IEEE defines to be NaNs will all be mapped to the single float NaN value.

Return the float value represented by s. s must follow the syntax of HexFloatingPointLiteral as defined by the Ballerina specification with the following modifications

• the HexFloatingPointLiteral may have a leading + or - sign
• NaN is allowed
• Infinity is allowed with an optional leading + or - sign

Return the float value represented by s. s must follow the syntax of DecimalFloatingPointNumber as defined by the Ballerina specification with the following modifications

• the DecimalFloatingPointNumber may have a leading + or - sign
• NaN is allowed
• Infinity is allowed with an optional leading + or - sign
• a FloatingPointTypeSuffix is not allowed This is the inverse of value:toString applied to an float.

Tests whether a float is finite. Exactly one of isFinite, isInfinite and IsNaN will be true for any float value

Tests whether a float is infinite. Exactly one of isFinite, isInfinite and IsNaN will be true for any float value

Tests whether a float is NaN. Exactly one of isFinite, isInfinite and IsNaN will be true for any float value.

Returns the natural logarithm of a float value Corresponds to IEEE log operation.

Returns the base 10 logarithm of a float value. Corresponds to IEEE log10 operation.

Maximum of zero or more float values. Result is -∞ if no args NaN if any arg is NaN

Minimum of zero or more float values. Result is +∞ if no args Result is NaN if any arg is NaN

Raises one float value to the power of another float values. Corresponds to IEEE pow(x, y) operation.

Round a float value to the closest integral value. Returns the float value that is a mathematical integer and closest to x. If there are two such values, choose the one that is even (this is the round-to-nearest rounding mode, which is the default for IEEE and for Ballerina). Same as Java Math.rint method Same as .NET Math.Round method IEEE roundToIntegralTiesToEven operation Note that <int>x is the same as <int>x.round()

Returns the sine of a float value. Corresponds to IEEE sin operation.

Returns the hyperbolic sine of a float value. Corresponds to IEEE sinh operation.

Returns the square root of a float value. Corresponds to IEEE squareRoot operation.

Sum of zero or more float values. Result is NaN if any arg is NaN

Returns the tangent of a float value. Corresponds to IEEE tan operation

Returns the hyperbolic tangent of a float value. Corresponds to IEEE tanh operation.

Returns IEEE 64-bit binary floating point format representation of x as an int.

Returns a string that represents x as a hexadecimal floating point number. The returned string will comply to the grammar of HexFloatingPointLiteral in the Ballerina spec with the following modifications:

• it will have a leading - sign if negative
• positive infinity will be represented by Infinity
• negative infinity will be represented by -Infinity
• NaN will be represented by NaN The representation includes 0x for finite numbers.
