On C Math Functions

C numerics library - cmath (math.h)

cmath declares a set of functions to compute common mathematical operations and transformations:

Trigonometric functions:

cos     // Compute cosine (function)

sin     // Compute sine (function)

tan     // Compute tangent (function)

acos    // Compute arc cosine (function)

asin    // Compute arc sine (function)

atan    // Compute arc tangent (function)

atan2   // Compute arc tangent with two parameters (function)

Hyperbolic functions:

cosh Compute hyperbolic cosine (function)

sinh Compute hyperbolic sine (function)

tanh Compute hyperbolic tangent (function)

Exponential and logarithmic functions:

exp Compute exponential function (function)

frexp Get significand and exponent (function)

ldexp Generate number from significand and exponent (function)

log Compute natural logarithm (function)

log10 Compute common logarithm (function)

modf Break into fractional and integral parts (function)

Power functions

pow Raise to power (function)

sqrt Compute square root (function)

Rounding, absolute value and remainder functions:

ceil Round up value (function)

fabs Compute absolute value (function)

floor Round down value (function)

fmod Compute remainder of division (function)
