Member Function Documentation

isinf() [1/3]

OFBool OFMath::isinf ( double d )

static

Determines if the given floating point number is a positive or negative infinity.

Parameters

d	the floating point value to inspect.

Returns

OFTrue if d is infinite, OFFalse otherwise.

isinf() [2/3]

OFBool OFMath::isinf ( float f )

static

Determines if the given floating point number is a positive or negative infinity.

Parameters

f	the floating point value to inspect.

Returns

OFTrue if f is infinite, OFFalse otherwise.

isinf() [3/3]

template<typename Integer>

OFBool OFMath::isinf ( Integer i )

static

Casts the argument to double and calls OFMath::isinf(double) on the result.

Parameters

i	an integer, i.e. OFis_integral<Integer>::value equals OFTrue.

Returns

OFMath::isinf(OFstatic_cast(double,i)).

isnan() [1/3]

OFBool OFMath::isnan ( double d )

static

Determines if the given floating point number is a not-a-number (NaN) value.

Parameters

d	the floating point value to inspect.

Returns

OFTrue if d is a NaN, OFFalse otherwise.

isnan() [2/3]

OFBool OFMath::isnan ( float f )

static

Determines if the given floating point number is a not-a-number (NaN) value.

Parameters

f	the floating point value to inspect.

Returns

OFTrue if f is a NaN, OFFalse otherwise.

isnan() [3/3]

template<typename Integer>

OFBool OFMath::isnan ( Integer i )

static

Casts the argument to double and calls OFMath::isnan(double) on the result.

Parameters

i	an integer, i.e. OFis_integral<Integer>::value equals OFTrue.

Returns

OFMath::isnan(OFstatic_cast(double,i)).

sqrt()

double OFMath::sqrt ( double d )

static

Computes the square root of a floating point number.

Parameters

d	the floating point value to inspect.

Returns

the square root of d.
